I think tipping in the sporting context has its origin, I think, in the worthy practice of a guest tipping the staff of his host to show appreciation for the services rendered to him, as a guest, by them though their employer is actually the one whom they are paid to serve.
Hence, a guest staying at someone's house to shoot would on this principle tip the domestic staff, as well as the 'keeper, to thank them for the extra effort they had expended as result of his visit.
I've no problem extending this to tipping the stalker and ghillie if I am a (paying, usually) guest on an estate - but one does start to wonder in the caseof a stalking guide or a commercial shoot, with whom you and/or your team have made a contract for the sport. Under the latter circumstance, I think that if a 'tip' (though I'd suggest this is not really what it is under these circs) is actually expected, this (and the amount) should be made clear before the contract is agreed - to avoid social and/or financial embarrassment to the Guns/Rifles and disappointment to the providers.
