My wedding in on June 18th and I reached out to our caterer today to get a final invoice. She responded by saying she talked to the venue and they'll probably need to add 2 more servers and 1 more bartender. There was never any hint that the number of servers/bartenders would change. Adding the bartender and two additional servers will increase our catering expenses by 15% so it's not something insignificant.
Also, when I looked over the invoice, the caterers are charging an 18% service fee for the wedding rentals we placed through a different rental company. The caterer just told us to mention who our caterer was to our rental company so that the caterer could see any updates to our rental list we made, in case they needed anything additional (like buffet tables). They aren't doing any setup/delivery at all. We had no problem going through the rental company independently and don't know why they should get a service fee for a third party company we're working with. Is this normal?
