Having come from a game shooting background i understand that it is necessary to tip the keeper at the end of the day. Now is it the same with stalking? I tend to tip and the end of a successful stalk is this the norm? is it also expected to tip at the end of a 'unsuccessful' (don't like that word) stalk? or is it not expected at all? If you do tip, how much is it per beast as a rule of thumb? more for a buck/stag than doe/hind?
