You know, I honestly never thought I'd write a review on a gas station, but this place is just so…read moregreat that I have to let others know about it. GCS has stores sprinkled all throughout the Green Bay area, and this location on University is the closest to my home. What sets this place apart from other gas stations is threefold. 1. It is locally owned. It is not just a Shell station, but a family-run company that's been in the area for a long time. 2. GCS hires a kind staff who answer questions and greet you with a smile -- a rare thing sometimes at gas stations. 3. The amenities - free air, free vaccuum, a great touchless car wash, full convenience store, as well as an A&W restaurant. It's weird to say 'I love this gas station,' but trust me, this place is doing everything right.

So I was referred here by my employer. When I initially called about replacing my stereo the sales…read moreperson was amazing. Answered all my questions. 1. When I brought my truck in today at 3pm and did t leave until after 6pm I was a little irritated because I was told last week it would take an hour. 2. The salesman who talked to me on the phone last week didn't say hello or give me the time of day(store was empty). He only told me he didn't have the part to fix my back up camera. 3. Salesman and receptionist promptly left at 6pm and I was told the guy installing the radio would come and get me. I would think the salesman would stick around. 4. They shouldn't leave transaction history up on their computer for everyone to see after they tore out of there. 5. The poor guy that installed the stereo was very nice and walked me through all the new gadgets. He was the best customer service I had there in 3 1/2 hours. 6. I truly felt after they got my $ they had no obligation to give me basic customer service. So far the new stereo is pretty cool! Do better Muntz staff.

My vehicle was supposed to be ready in 2 hours. I understand the scope changes, but a call with an update is expected.
