I work at a tiny gas station/convenience store, and it's not in the best neighborhood, but most of the customers are alright. Not this lady, though.
A few weeks ago a middle-aged lady came in and browsed around the store while I took care of other customers in line. After about 10 minutes of going around our numerous (3) aisles, she came up to the register with some snacks and toiletries. I'll be M, she'll be PL, for Plate Lady.
M: (punching prices in) Anything else I can get for you?
PL: Oh, I need some cigarettes. (tiptoes and looks behind me)
So, I move out of the way and when I look back up at her, she's leaning against the counter.
PL: Can I get a pack of (some brand that's on the wall behind me)?
I go to grab them, and when I turn back she straightens back up (from looking at something in her purse, or so I thought).
PL: Actually, could I get two?
I grab another pack, but keep looking at her as I do.
M: Alright, will that be all?
PL: Yes, thank you.
She pays, and as she leaves I hear a soft thud in front of the counter. I thought it was something on the shelves that had fallen off, so after she left I went around front to check it out.
It was a pack of paper plates.
I checked the cameras and sure enough, she'd been balancing them between her thighs and the shelves, hoping that I'd look away long enough for her to stuff them in her bag. Some people.
