So I confirmed everything with my rehearsal dinner venue and I gave her what I had for my total including the 18% tax and 6.25% state tax (ugh). Her total was $40+ higher than mine. After we went over the figures, her tip was higher than mine. I asked why and if she figured the tip on the total WITH tax and she said "yes, if you were to come in for dinner for two, you would pay the tip on the total including the tax." Hmmmmm...what are your thoughts? What would you do in this situation?
