I have only one real pet peave. AND, it's already been mentioned.
I work nights. Can't help it; that's how the restaurant industry works. Because of the price of gas, I will make one weekly grocery run. However, since I drive right by a super wally world on the way home, I will often stop to pick up something I forgot on the weekly trip. Used to be, this was a gallon of milk, about one a day. However, this policy of shutting down ALL self-serve registers at 10 pm, closing down all but 2 - 3 of the regular registers, and only two "express" registers, WHEN THE STORE IS PACKED WITH CUSTOMERS UNTIL AFTER MIDNIGHT, make NO freaking sense to me. Many times I've waited, patiently, for over 20 minutes to buy one gallon milk, while it only takes me 4 minutes to park, walk into the store, back to dairy, grab the gallon, and walk up to the registers.
Up in MI, the Meier's would leave their self-serve registers open all night.
Luckily for me now, the kids don't drink as much milk as they used to, AND, I've got a couple other stores that I can buy milk from if I need to, with the same or lower price/gallon on milk, and a lot less waiting time at the register.
Peace, Love, and Vegetable Rights!
