I love cheap gas, as I am currently unemployed and looking for work. So, I go to Arco, because they're the cheapest in town (yay). The one closest to me always seems to have craptacular service. I don't expect a red carpet rolled out for me, but is it SO MUCH to ask that I get a "hello" and "have a good one" from the cashier? Every time I go, they hardly make eye contact, don't greet, and to my recollection, never thank me or say "have a good one". That, IMO, is basic customer service. Someone walks in, you look them in the eye and say "Hello"....the customer says what they want, gets rung up and pays, and the cashier says "thanks, have a good one" or some variant of that.
I think it is incredibly rude for them to have their friends lurking around the counter, having a personal conversation while I'm trying to tell the cashier I need a couple quarters for parking. Basic service!
Not horribly bad on their part, but annoying on a regular basis. See the first two sentences of my post to understand WHY I keep going back there.
