Actually I don't hate it at all. I like the idea of performance based pay and rewards.. and champion it. I just expect consistency and some level of rationalization in it as well.
Leaving 'expected' tips. blindly, for whomever is in the room next, PRIOR to service, for staff not hired with the expectation of tips, does not meet my standards for gratuities for great service. It goes against nearly every construct of what justifies gratuities in every other situation -- that's why I don't subscribe to the 'suggested practice'.
But your post doesn't actually address the points. Yet I'm sure in a few hours, people will act like the counter points never existed.. and the emotional arguments will drone on.
