There's also the fact that if all they're getting is a tall boy, they can't be my kind of drinker. 16 oz would be down my gullet in half an hour, and wouldn't so much as buzz me. If thats all I'm getting, it was a waste of a couple bucks.
The reason I was rotating my buying, avoiding clerks, etc, was shame and fear. A normal person buying a single beer at the end of a shift probably doesn't feel that, so they have no reason to question buying it in the morning if that's their downtime.
If I saw them back to restock several times a day like I did, I'd relate easier. But as has been said, it's not my business, either.
