I've been there twice and probably won't go back.
Both times I was there filling up my car their windshield guy came over to comment on the chips in my windshield and try and get me to use their service for replacement. Although he was courteous, I just don't agree with the tactic and would like to just get my gas and go without having to fend off some random dude trying to get me to give him my insurance information.
Last time I was there I couldn't get the pump (16) to read my credit card. I tried 3 cards before giving up and moving to another pump. This pump accepted my card without issue. After I was done, I went inside to tell them about the card reader at the pump. The woman behind the counter replied "yeah, I know. We've been having problems with that one".
I felt like asking why they didn't put up a sign...or perhaps, they get a kick out of watching people try over and over to get the reader to work. Either way, screw them. I'm out.
There's other places I can get gas without the aggravation.
