I stopped giving tips. I did for a while, but then stopped. The rates are outrageous all over. With inflation they should say 1.5/hhr and 2.3/hr, fine. But 1.8/hhr and 3/hr? LMAO! I succumbed to this a few times this week, and will again, but am going to transition back into my higher end, less quantity mode when I am done with graduate school.
