I'm going on a hunt next month and the written expectation is a 10 % (of the hunt cost) "tip". The "tip" is to be paid unless there is something wrong with the service, in which case the owner wants to know what was wrong. The so called "tip" is not really a tip in my book, but an expected part of the contract price, though perhaps unenforceable at law. Another hunt, the cooks implied that they hardly got paid anything and relied on the tips. Always wanting to know whether I liked the food they cooked (as if you can just say it was average!) and hanging around until they got their "tip". These are not inexpensive hunts, so I just consider the owner's are skimping on wages so the hunter helps pay their wages, via a so-called "tip".
