The female colleagues I've travelled with appear not to get hassled though I suspect anything can be arranged for a price.

As a tip to the other readers of this thread: if you're being hassled by persistent ladies of negotiable affection, never attempt to get rid of them by saying you're gay.

I'm told (by several very reliable sources who were there) that one of our employees once got so p****d off with the hassle he got in a dodgy African bar, he decided to tell the nice ladies he was gay. Unfortunately, their pimp was most accommodating; it got quite entertaining when a rather muscular local approached him a few minutes later.
