Tipping in the service industry

[Gawdzilla Sama]

I broke my math bone when I was in the 5th grade, and it never healed properly. Now my phone has one of them adding machine things. (Not "abacus", something else.)

I tip what I personally feel is right, and it always ends up being more than what is considered appropriate.

One day after a restaurant experience, I learned through my phone that I tipped way more than I should have.  Oh well, that server deserved it.

I have a lot of fun with tipping in non-US locations. Mostly watching Americans try to figure out how much tip is appropriate. I don't know if they're afraid they'll get shot if they do it wrong or they don't know how many dollars are in a pound. I cheat, I look it before going.
