As the fee itself is for a service it never occurred to me to tip... not that I'm against the idea, I just always thought of tipping in this industry as what some MP's ask of clients in exchange for additional services.
However, if I've had really excellent service, I certainly am not against leaving a little bonus on the bedside to show my appreciation... it just never occured to me before.
So this begs the question... if you're feeling inclined to leave a tip behind for excellent service, what colour would it be? Purple? Green? Surely not blue (Yeah 'dat was some great head bay-beeee! Go buy yerself a beer!)
