I went inside to pay for my gas because it is cheaper to pay in cash. I walked in & the 2nd register opened right where I was standing. She announced that she could help the next customer. I put my $20 out & said "$20 on #4 please". She replied, "The line is over there." pointing to the far side of the counter where there were 4 other people on line. Perhaps I wasn't literally next, but I was literally standing in front of her. I could see if I had a handful of items to buy, but it takes 10 seconds to click buttons to put $20 on gas pump #4. What a rude attitude. I waked out & went to gas station up the street. No attitude there. The bonus was that I was able to use my grocery store discount & save $0.60 per gallon. Woohoo!
