Way to go, Graham! There's a prime example of an alpha-male feeling threatened and compensating by trying to re-gain the high ground with his mouth. I received a few choice comments myself last week at the trade show so I know what its like. Yagotta be quick with the come-backs to effectively squelch the assault in your favour. I guess when you put yourself on center stage, you gotta expect the occasional hoot. Is it worth it??? 8)
