Sounds like an urban legend to me.
Not if he were having dinner with a European.
"Sounds like an urban legend to me."
Maybe so but I think you're missing the point. If I were a salesman and we went to dinner together and I ate like a friggin pig would you want to do business with me? I represent myself and my company and if you think about it, maybe that's the kind of service you'll get from me and my company. Would you want to do business with me? If on the other hand you ate like a pig I would not do anything to make you feel uncomfortable.
