Long lines but cheap gas. Lines can get little hectic but if you go within the right times you'll be fine

Cheapest gas that side of town. Convenient location great customer service. No matter what time of day I go in there, they're smiling and swing back and forth from one register to another so customers are not waiting read more

Always the cheapest gas, currently $3.09, which is better than anywhere else we've found. That's for cash or debit. Small convenience store. The gentleman running it seemed a little stressed and the pump shut off after it took my card. I had to get his help, which he quickly gave, and others had to wait inside the store. I'll keep coming back as long as their pricing stays so good! read more

The man inside is very rude. When a customer comes in and questions why you charged them more and you tell them because they are using a credit card that's fine. However, it is rude and very unprofessional when a customer asks where is the sign informing us that you charge more for using a credit card you cop an attitude and respond out there and get within my six foot space during this pandemic and rudely start to tell me to make sure I look at the sign carefully (which is tiny, at the bottom on the ground, and not even facing a direction for people who come in to see). And then when I say thank you just so I can leave on a good note he rudely comments make sure you read next time as he stalks around to the back of the counter and ignores me when I say excuse me! Don't make snide remarks to people when you are in customer service. And there will be no next time when you behave that way to a paying customer. That's very presumptuous that I will give you money again for anything. Inappropriate behavior and inexcusable. And he refused to give his name. Be advised watch your receipts and look at all areas for a so called sign. read more

This station did not want to provide with gas. I need to get to from A to B in a hurry. I had$ 21.16. The .16 was in pennies. The cashier said "i have to many pennies" and refuse to take my money, all because i had pennies. They just lost a customer. So much for picking up my kids. read more

This is my favorite gas station. I get all my goodies from here. They have best prices on gas and fountain sodas.

Horrible customer service. On my last visit, the pump I used leaked gas onto my car and my shoes. When I went to let the attendant know, he came out and kept pressing the nozzle handle to check the leak. I asked him not to do that, because I specifically put in a certain amount because I had checks and some charges pending to my account and my payroll check hadn't cleared yet either, so I didn't want any checks to bounce, to get a returned check fee, or insufficient funds charge. He finally stopped and I explained why I told him to stop. He had me call his manager Aki (sp.?) and I told him what was wrong. At this point, I still hadn't received an apology for the leaking gas or the fact that the gas I was paying for was on the floor. His solution was to just refund my money. I was fine with this. The attendant gave me a receipt and said the money would be credited back to my card "right away". I did not get a credit, been checking my online statement for 5 days already. I messaged the manager back and he did not get back to me. I will tell my acquaintances not to do business here. read more
