Heh, realizing that my previous post there was pretty one-sided. I was too focused on responding to the idea of "If their salary is inusufficient let them take it up with management" to remember to include anything else. I should point out that I also don't add additional tips to room service and do think tips should be adjusted according to service level. And mandatory tips are not only annoying, but sometimes they do more harm than good on behalf of the server(s)! I used to go to a monthly dinner gathering that would vary anywhere from about 8-20 people. Normally this would be enough that they would add a mandatory tip, but they *knew* better after a while. They knew that we actually tipped way more than the mandatory tip for putting up with us and never bothered to add anything beforehand. On the other hand there are cases in groups where one or two people are cheapskates and the tip ends up being light, even if the service is fine. That's what it's designed to protect against, but I'm guessing it more often protects against getting a *higher* tip.
