Hi!
We are having a buffet style wedding. It is a per-person price and travel, serving, clean-up (of their area), and disposable dinnerware (I likely will buy/rent my own nicer stuff) is included. Gratuity is not included. They are only scheduled to serve for one hour.
I'll have right at 100 guests. I don't know how many servers they will send yet, but how do I go about tipping? Do I tip 20% of the catering bill? Is that split between servers — or per server? Or is there a common "rate" for an hour of service? Not sure how this works!
