I have never. Seem this happen, but it would be terrible if someone did this.
Huh? Exactly what are you talking about?
You mean when a customer needs help at a Uscan you're not in control of and they flag you down for help?
I help them out most of the time. But if I'm too busy with my own customers, I tell them to wait for the attendant to come help them.
I certainly do.
