I guess I'm not the only one with this problem. I have one customer where the boss is always away on Wednesdays and one particular employee will hang around and always asks "Is it broken?" I've got the machine apart and spread out and he has to ask me that! I've got another customer whose employees will stand around watching me work, that's when the air hose comes out and I air clean the machine. Works every time.

The worst ones are the ones that follow me around. I'll be on one side and they'll stand back and watch. So I move over to the other side and they walk around to that side to watch. I like to think they've never seen anyone work before and it fascinates them!
