It's not uncommon for a cashier to send a customer to the manager once
the sale has been finalized. It keeps the line from being slowed down,
and it adds a bit of extra work for someone who wants to return an item.
Okay, once, something
happened and I had to start all over, and they did make me go to the
return/customer service counter to do it.

That's what they do at the main supermarket I go to. Once you're rung up,
you're done and if there is a price problem, etc you have to go to customer
service. I'd be surprised if Costco cashiers would do it either.
