I asked for a different sales person because the one who approached me had a big ring in his lip. He looked bizarre.
This was at an Apple computer store, and the sales person was the greeter at the door. I told him to his face that the ring in his lip distracted me from having any serious conversation about computers with him and that I wanted to speak with somebody else. Somebody who looks like a fruitcake should not be allowed to personify an upscale, retail store like Apple. It reflects poorly on the entire company.
