Who me?

I wanted to buy something the other day at the Chandlery.
I was a customer but the shop assistant was too busy to serve me and I wanted them to ring the supplier for some measurements. So what did he do.
He handed me the phone and said you ring.
Who Me?
But I'm the customer, I would think I deserve some service. Not likely. I phoned the supplier and got the information and then
went to another shop to order the product. One that gave me exceptional service and did a discount to boot.
Now that is service.
