I seem to get invited back so maybe I'm tipping too much....
What I was trying to get across is that I would expect a good tip for loading and I equate that to a days graft of someone guiding me on Red's say... Then if your somewhere nice there's a tip for the pony boy etc...
Also im quite unfit and I try my best but they inevitably end up dragging me back as well
Interestingly some of the worst tips I've ever had are from the richest people!
