The cat food lady
We have a lady who does drive ups at our store. Often at full cart, somewhere between 25-30 "bags", and it's all just pallets of cat food accompanied by either Gatorade, soda, or tissues. I really wonder if she's a reseller or something. She often sends in her sons to pick them up, and they are darling, but I've had an encounter with her herself once and it's... Crazy. She demands that the items are stacked in her car in an insanely specific way, and as you're stacking the items, she will not let you put the next in until she scrolls her insanely long checklist, marks it off, then instructs you on where to put the next one. Luckily the one time I encountered her, I had a lot of time and it was rather slow but according to my coworkers, she will do the same when it's busy. Apparently they've even had to tell her off and be like "I have other customers to serve" and leave her with the cart. Anyways, just a really Interesting lady all around
