Ok,I don't live in the U.K. But in Ireland. Our societies are not too dissimilar. I also work as a pigeon guide during the summer months and in January/February when the pigeons are tucking into the winter rape. Most of my clients are Scandinavian and those societies do not tip customarily. My regulars often bring me a bottle of good snaps as a gift. We are to all intents and purposes friends. It is customary in Denmark to bring a gift to a hunt. Newcomers are often writhing with anxiety about how much to tip. Too little can be interpreted as rude,too much as extravagant. I am perfectly happy to tell them that they are paying an agreed rate and I don't expect anymore. Restaurants if there is no service charge yes 10% is acceptable. Cabs/taxis,as a rule we don't tip very much. Buying hunting anywhere is fraught with danger. I see stories of people being charged a stalking fee,fair enough, a shot fee,WTF ! What in the hell are you out for ? Of course you are out for a stalk in the hope of finding the right animal for you. But an additional charge for shooting one ? An additional charge for carcass damage. What do you expect with a boiler room shot ? Trophy prices should be agreed beforehand and the guide should assess it. If it exceeds his estimation,tough titty.
