Maybe my I have standards that are too high. All customers or potential customers should be respected. I don't expect people to beg for my business, but be polite.
Arrived at this place at 6:30pm on a Saturday all of the lights were on and the doors wide open. A guy loading a truck walked up and pointed out that they were closed. I said ok and was about to ask if they did tire repairs so that I would know if I should try again during hours, but before I could form a sentence hit nastily spit out can't you see the "open" sign isn't lit, next time look for that.
Maybe he'd had a long day, maybe I'd had a long day.... Just came off rude and I choose not to do business with people like that.
