I work in sales in a very male dominated industry. I used to be the only woman in the UK salesforce at my old company. I well remember the email stating that any expenses for "gentlemens' clubs" would not be honoured etc and the outrage of some of the older salesmen. I, of course, laughed my arse off!
I like the comment that the people who organised it had now left the company. I don't think I'd be happy unless everyone who attended had gone. And, not wishing to show any sympathy, I wonder if any/how many of those who did attend felt they had to?
Makes my blood boil!
