Probably shook him up but if he stays in the game, it will be good training for him. I can remember when I was a teenager in a Saturday morning job at a department store and we were given a line (long lost to time) to greet people with. I thought then that it sounded fake and I would hate it directed at me so I continued to smile and say "Good morning. How can I help you?". Since then we have become so used to these phoney statements and questions that we don't even notice. We all know that the checkout staff and salespeople could not care less how we are and certainly do not want to know. I found it uncomfortable and slightly offensive before I had cancer. So, as far as I'm concerned, turn it straight back if that's what you want to do. I relish my entry into grumpy old womanhood.
