Adult VBS leaders can be the worst.
I was working crafts one year and we needed all the chairs for the kids, but one lady refused to give up her chair. Later, at that same table one of the girls peeled too much of her craft (we were making sticker signs with glitter) and the same lady insisted I get the girl a new one, but no matter how many times I told her we didn't have enough supplies for do-overs, the lady just went and ripped up the girl's craft.
The little girl didn't even care that she'd messed up, all the fuss was caused by that one woman.
