I filled my car with gas and requested a receipt. The gas pump must have run out of paper and no receipt was printed. I went into the gas station to request a receipt. The doors were locked but the attendant was present. He would not open the door or acknowledge that I was waiting for about 20 min. Eventually he unlocked the door. I told him I needed a receipt. He ignored me, and left the gas station through a different door. It was about 9pm and there was no obvious issue or danger. He just decided to ignore me, during the posted operating hours of the station!!!
Unreal. All I did was ask for a receipt!

Gas was pumping 1¢ at a time. Not sitting there for 30 minutes. Pathetic

The tall black guy over here who sounds a little light-spoke is insanely rude. If he’s there just find another business to promote. Don’t give him your money.

This is the only place in Denver, that I buy my gasoline. Prices are competitive, solid (good) customer service. Been going here for the last 6 years.
