The only service work I get at wally world is battery replacement. I pick out the battery on the shelf, so the + and - are on the right sides. If they put it in the wrong way around, the cables won't reach to the back of the battery box. If they try to cross the cables, they won't reach. Hard to mess that one up. I won't let them near my '51 Plymouth because that is positive ground and I'm afraid they might try to put a charger on it backward.
