I had an interesting moment at work. A customer was waiting for service at the jewelry counter, so I paged for a cashier person to come over. As I was walking away, his wife came up, and said she had had no luck finding someone to help them. Then the man pointed at me and said, "She paged for us."
This was no sales person hoping for my business, nor even a co-worker with an obligation to be tolerant, but a customer, a stranger.
Added to this, I was working with a new co-worker, and introduced myself as Dorothy, but gave no explanation. Then, later, he was talking about how much there was to do, and said, "You aren't superwoman."
Between these two moments, I think I floated until out lunchtime.
