Obviously none of this is bad service - the poor guy was clearly getting sick and regardless, he wasn't on duty. As the cashier finished checking me out and I signed the credit card screen, I decided to make use of the bottle of hand sanitizer they keep on the checkout counters for customers. I'm not really a germaphobe, but it's the kind of thing where if you actually see someone sneezing/coughing all over the place and touching everything, I feel like I should use it if it's around. So I thanked the cashier as I spritzed some sanitizer into my hand, and she gave me a dirty look and snapped, "You know, we keep things really clean here, and that stuff just kills good bacteria, anyway."
Maybe so, but I'll take that over salvaging any bad bacteria from a guy who's coming down with the same thing as his apparently deathly ill girlfriend, just this once.
