Mmm... tipping wank. Delicious. I don't tip baristas at Starbucks, but I do tip at Coffee Bean and Tea Leaf as well as family owned type places. Why? Well it's a bit of a long explanation... According to my friends who are baristas (one at a Coffee Bean and Tea Leaf and the other at a family owned place) Starbucks uses a lot more automated machines so it's more about just pressing the right button than having the skill to make the drink.

Also, the easiest way to tip is to just double the sales tax (at least where I live, in Los Angeles). Very little math required.

However, I'm always unsure what to tip hair dressers and pedicurists (I'm pretty sure that's not an actual word)... Usually, it's a couple of dollars, but I have no idea what the appropriate amount is.
