Walgreen's checkout lady here.

Love: the endless succession of Getting Things Done. Each person successfully checked out counts as a task accomplished, which gives me a good feeling. Plus I get to restock cigarettes and candy, which is a good feeling, watching the mountain of empty cardboard shipping cartons grow. Seriously. "Hah!" I think. "That'll show you, Ms. Management Person who doesn't think I can restock this whole entire cart full of candy outs tonight!" I win.

Hate: when people are snarky because I card them for cigarettes (Hey, I'm not going to jail for a $4 pack of smokes), or, worse, when their abused Link card won't run on the pinpad and they have to move all their stuff over to the other register, with its newer and more sensitive pinpad, which can read their Link card that they keep in their back pocket, sit on all the time, and apparently use to scrape frost off their windshield.
