Horrible, here goes- If I could give NEGATIVE stars I…read moreabsolutely would! I do not recommend going here. I have more than a few words about the way they treated me here and for NO REASON! So, Last Friday, I had a tire blowout incident- by Sunday I needed to replace the wheel/tire. So I found the closest tire shop to this Circle K. As I am having my car serviced, im told that they do not accept debit cards- cash only! So I said, "that's fine- Ill go to the ATM" i walk to Circle K, use the atm, say thanks and leave...head back to tire shop. I get there and realize that I've left my wheel in moms vehicle, and now need to purchase a wheel as well. I say, "ok, ill go back to the atm" so I turn around head back to Circle K. This time I needed an odd amount($30), and ATMs give even bills. So I withdraw $40 and am already stressed at this point, I walk up to the counter and ask politely if they can do change for a 20. The clerk rudely says "no, I won't do that, we dont have change here" so I walk to the drink cooler and grab a redbull. I set it on the counter w/1 hand &a 20bill in the other, ready to just purchase a drink. I figured in my head that if they cant do change, they can SURELY let me have my change after I buy something with MONEY, right? NO, the clerk got nasty and disrespectful with me and actually told me this-"you're gonna have to get closer to 20 than that!" Basically telling me that I couldn't just purchase the redbull, I was expected to spend more of my money at "his" store in order to make the transaction and get my change. He goes on to say this after telling me that no I cannot buy this drink...he says-" well- the cats outta the bag now that you just need change so, im not selling that to ya" so i walked out, no drink, or change, no transaction whatsoever and straight across the way to the liquor store- they helped me right away, I told them briefly what had happened and they were so helpful and kind. I offered to buy something and they said there was no need-and handed me change no problem. Apparently they know of the CircleK clerk, he must have a rep for this kind of social misbehavior- Needless to say that this man needs etiquette lessons and maybe a BUSINESS CLASS so that he can learn that you dont ever treat someone that way in a "professional" setting, a stranger, especially your own repeat customer, and a person that was IN NEED at the time, as well as low on funds, like honestly I couldn't even AFFORD THE REDBULL BUT HE WAS SO RUDE I JUST NEEDED MY OWN MONEY BACK, (BUT LESS OF IT!!!!) Like dude, im trying to give money to your business in exchange for my own $$$ seems like he just lost a lot of customers....some people's children.......

The owner/operator of this place is an absolute douche-bag... Last summer my wife and I, along…read morewith our two kids and my 95 year old grandmother decided to do some fishing at Carter Lake. On the way home, my wife wanted to stop at the Pump House, (right next to this gas station) to get a refill on a growler we bought there a while back. I made a U-turn and stopped my truck on the gas station property and let my wife run in to refill the growler. I sat IN my truck, along with my grandmother and two kids, with my truck running. My windows were up, air conditioning on when I noticed my wife pointing at me and pointing towards the gas station building. I rolled down my window to hear my wife say... I have to move, that is a "No Parking" area. By this time, the gas station guy (D-Bag President) was YELLING at me to move my truck and did I not see the "NO Parking" sign?????!!! I was like... no SIR... (being respectful here...)... my apologies, but I did not see the sign and I am NOT parking my truck here and leaving it. I was just waiting on my wife to run in and do this quick errand and we would be on our way. This man was having NONE of it. He STERNLY asked me again to MOVE my vehicle. (Keep in mind... there was ONE other car getting gas at this time. It was not like I was holding up a line for other cars that were waiting on me to get gas... NO... I was FAR away from the gas pumps, bothering NO ONE... also no one else on the gas station property) I stated my case AGAIN... I said something to the affect of... "hey... I am NOT parking here... just sitting here waiting on my wife who will be back in no more than THREE minutes..." He said something like... if you do not move, I will call the police and have you thrown off this property... I then looked at him and said... WOW... I am really HURTING your business by sitting here huh!!?? (I had other very choice words for him... but I was not going to go there in front of my kids...) I then proceeded around the block, then came back ON THE STREET, next to the sidewalk, by the curb NEXT TO THE spot I was just at, but NOT on this guy's property. By this time, the wife came out, and we were on our way. Mind you... I realize I was, 1) on private property, 2) in a no parking "area" that I did not see the sign... my fault. I get that... But as a business owner... don't be a complete ... you get the idea. He could have been like... Excuse me sir... but this is a No Parking area. If you are going to be just a minute or two, that is fine, but please don't leave your car here. Thanks... There are different ways to handle a situation... needless to say I won't be doing any business there ever...
