Best convenience store in San Bruno, California (CA) 2024

Had a slightly surreal experience there on Saturday morning around 10am. I had a full tank but wanted to double-check before returning to Alamo, so I had paid $10 ahead to use the pump. However, when I went back to the pump it didn't work. I went back in and they guy came out and fiddled with some buttons and went back in with no explanation. It still didn't work, so I went back and asked for my money back and he just ignored me looking bemused. I had to get off for the flight, so just left without filling up. Okay, only $10 lost, but it was most odd. ADDED NOTE: I just checked my card and the $10 payment that was pending never went through. No charge made. No harm done. ~Douglas
