The lady that did my nails at the salon is so upset right now, because I didn't tip this one time.
Well they kinda depend on tips. Why didn't you tip them?
They were unpolite to me and I was dissatisfied with their service.
Even if the service wasn't good, you should still tip a bit. Service workers depend on tips to live so you should tip a bit but reduce it if the service isn't great.
I'm never going to tip them, I don't care about how they feel.
If you don't plan to tip the nail tech you should start doing your nails at home. You'll save money, and you won't upset people at the salon.
