I do this every chance I get. Usually with wine bottles. Most cashiers will just turn the belt off and make me move it down. That guy looks about as sharp as the cashier I had at Walmart that snatched up a box of shotgun shells and had the bottom of the box pop open. He carefully put them all back in the box and picked it up the same way, dumping it again. I just had him throw them in a bag. I was happy that it wasn't a bulk box of .22 ammo.
I once was behind a shopper who put his credit card fown on the belt. Watched it slide under the end, out of sight. I switched aisles, not knowing how long they'd need to find it.
I think she may have been using that stool since she was a little girl. I was always ready to push back, but that was a pretty stout shove. Last time I milked a cow was almost fifty years ago.
If you have to care for someone with long hair who is restricted to bed it can be a problem dealing with their hair. The easiest solution is to gather it into a ponytail on the top of their head. It stays out of the way when they roll over and doesn't get in their face. They might look like Zippy Pinhead when they get up, but it's a practical solution while in bed.
My hair is longer than hers and I would NOT want anyone to see me like that. I don't think I could pull off the look. LOL
