Opinions Wanted -- Tipping?

[kybearfuzz]

I'm usually a good tipper when it comes to restaurants unless the service is just horrible. However, when it comes to other services, I have no idea how much is an appropriate tip.

What do you consider to be an appropriate tip for the following?

1. A taxi ride (use $12 as an fare amount if you want)?
   
2. A haircut?
   
3. A hotel maid service?

Are there instances, like the maid service, where you don't feel you should leave a tip, or do you leave one if the room is necessarily messy?

Just curious...

I never thought about leaving the tip just on the day you leave. I did not even know to tip housekeeping until recently. Granted, I do leave the room pretty much spotless, but they still have to clean several things like the bathroom. Good point as well by leaving a tip attached to their card to make it clear that money is for them and not left out casually.
