I was a customer next in line when I heard the dreaded words, get me your manager coming from the customer ahead of me. The cashier just told her co-worker, just do it (whatever the customer was wingeing about) and the customer still was ranting about whatever. I went up to be served and I said, damn I hate customers. Got given a funny look until I explained, I work in retail too. Both cashiers gave me a smile and said, oh you're one of us. At least it broke the mood the last customer left.
