I look at it from the angle what if it were me? There was something out around the holidays about who you should tip and what was appropriate, although I know not everyone agrees with that. Fact is there are just some jobs that that's how it is and what if it was me on that end of it. I've been there also so I tend to be a bit generous with tipping. Waitresses i think usually give part of their tips to the bus boy/girl and hair dressers to the shampoo girl or staff that does the cleaning up (at places like Gene Juarez) etc.
For me personally when there are people that provide me a service and go out of their way for me then I like to show appreciation when deserved as is customary and when appropriate. Obviously I don't tip my attorney, but I would send a card if warranted and that kind of thing.
