Yup, I felt like a total dick. In these situations it feels doubly bad because I’m perpetuating a stereotype about Asian people being cheap.

Here’s the question though, would you find it harder or easier to not tip a bathroom attendant if they were dressed well or dressed badly? On one hand, a well dressed attendant probably gets more tips because it gives the impression that people just have to. Then on the other hand if they’re not dressed well then it probably means the job is even crappier so maybe they need the money? I guess quality of service depends too.
