I'm stuck with the "normal" sized carts and no self-checkout. I walk with a cane so I pop my cane in on one side of the cart. I use the kiddie seat for my purse. As for self check, I can never get the bags to open and don't want to hold up the line with fighting with plastic bags.

I figure I showed up, put stuff in the cart, and got the cart to the line, let the cashier do the rest.
