I've had a customer call, claiming to be from one of our other stores, asking to see if we had a certain item (which we did) and then asking us to hold said item for a particular customer. We would get calls here and there from other stores, but we never held items for anyone, ever. It was a resale store chain, and this was corporate policy.
When I asked what store they were calling from, they replied, "The east-side store."
When I asked "What store number is that again? Because I want to let your manager know that you're trying to get me to violate policy."
They hung up.
I called that store immediately, and was told no one from that store called us. Wish our store phones had caller ID. Customers can get devious.
