46's? I assume you state has 45 minute lunches and people call them 46's because you have to wait an extra minute to punch back in? Makes sense, but never heard that term.
As for the other responses, I agree with all except Sacramento's if I understand it correctly.
I'd beat a cashier over the head with something, preferably something pointy, if they combined 5 reshop carts into 1. That's just making it harder for the people that have to push the items to the floor.
We have carts 6/7 combined as one two-tier, and 2/3 combined, but none of the other make sense to combine.
6 is toys, 7 is electronics, 2 is pets/chem 3 is HBA. ie. 2=3=A Block 6/7 = E/F (except seasonal, that is its own cart).
