Starting with the people who knocked on the door to our house at 6:30 a.m. demanding that we open the sale up immediately! The sale time was 8 a.m. to 1 p.m. and this was posted in the newspaper ad. My spouse told them no and they threatened (promised we hoped!) to not come back. Which was fine with both us.
Has anyone ever asked someone who makes that "I'll take my business elsewhere!" or "I won't be back!" statement why exactly they think they're important enough that anyone in the world would care? I'd be curious to hear the answer, though I imagine it'd really come down to the usual boring arrogance. I've always been either an uninvolved bystander or working when I've heard it, so I've never been able to ask.
Sale was open all of five minutes and a person came with a set of salt and pepper shakers priced at $1.00 and asked if I would take a quarter for them. I told him no, that the sale had hardly started and I wasn't doing any discounts now, but that he could stop back later on this morning and try again if he wanted.
He then told me he couldn't do that because they would probably be gone by then.
Good lord. And I'm guessing there wasn't even a smidgen of shame or self-awareness to go with that pronouncement.
Then there was the guy who showed up about 15 minutes into the sale with a 100 dollar bill and wanted to buy a one dollar item. While I had change, I didn't have change for that much money that early in the morning. He asked me where he was supposed to get change for the other garage sales and I suggested that he stop at the local Quik Mart and ask them. He did manage to find a dollar bill to pay for the item.
The hundred dollar bill nitwits can be the bane of my existence at the library. They get one or more hundred dollar bills and then as far as I can tell their first reaction is that they must immediately come to the library to pay their 75 cent overdue fee. We'll take it if we can manage to give change without too much hassle, but some of them get a bunch of fives, ones and even quarters back. The ones who insist, at least. If we don't have enough tens and twenties, most of the people who "only have a hundred" will miraculously manage to come up with something smaller.
I've had more than one person tell me that their bank gave them the hundred and they just want to break it. Why they didn't request smaller bills from, say, the person who gave them the hundred, who works in the big building full of money, I have no idea. I've never been able to think of a way to ask that wouldn't sound like I was calling the patron a nimrod.
