I'm sympathetic to the idea and curious to see how it works for the author. A clear subset of salespeople have a distinct entrepreneurial streak. They work in sales because, similar to being a business owner, you get paid based directly on the value you provide. You would definitely lose these people, but depending on how strong your sales systems are, that may or may not be a net loss to sales. Losing entrepreneurially-minded people from your company, though, seems like a general negative.

Incidentally, one of the commenters had an effect on me quite opposite to his intention. The commenter noted how much he liked restaurants where the tip is included. This is completely foreign to my experience. My experience is that tipped service is consistently among the best service.
