Small stakes, live tipping advice?

[Hydrant]

Here is a question for you who play live.
I am getting ready to play live so I am interested in tipping culture.

If I play limits from 3/6 to 6/12 what are some general guidelines for tiping, like when and how much?

Does it matter if you losing or winning?

Any difference between US and Europe?
