So I just got the proposal from my caterer, who will also be in charge or our rentals, but they will be outsourcing it through another company. She tacked on an 18% gratuity charge for the food, which was to be expected, but ALSO for the almost $2000 in rentals and $1800 in waitstaff fees. Does this seem right? The entire waitstaff is $25-30/ per hour per person, tipping on top of that seems excessive, and tipping 18% on rentals? Seems like an overkill.. am I being cheap?? Is this a normal charge?
