Hesitate slightly to wade back in here now that Knob Rob has added his perspective but here goes.
I am a successful salesperson; I have often been salesperson of the year; I usually work on multi-million pound deals (to set the scene); I work to put food on the table and feed, clothe and educate my daughter (and myself, come to that). Oddly enough, I have never been offered a male prostitute as a "reward".
I was once in a situation where one, male, member of the sales team arranged for an escort to join us all at a celebration in the West End. I was
about this and would have let it go but the rest of the team present (all men) were not so amused and he was asked to leave. He was eventually sacked for "expense irregularities".
I have worked with people who I know use prostitutes and escorts but the majority of the men I've worked with have been decent and would no more want to be rewarded by a company orgy than they would want to boil their heads.
