Activity for Rose

Hi! My wedding is next Friday in New Jersey and the owner of my venue gave me envelopes to tip the following. I am also paying a 22% service fee. What is reasonable? I have no clue. Maitre D Captain Waiters Bartenders Bridal Assistant Chef Thanks! ...

I have a meeting tomorrow with one and I want to make sure I'm not being ripped off! And any questions I should ask them? Thanks!!
