These days, everybody seems to be on a budget, so what could be worse that having an unexpected bill come your way on the day of. Unfortunately, many brides run into this same problem. One of the biggest unplanned expenses of a wedding comes in gratuities. This is because many couples think that the “service charge” is a tip for the event staff when it’s actually an additional fee that the catering halls charge. But if the service charge isn’t the gratuity charge, what is if for? To cover their own cost for hiring servers. The cost of this gratuity is typically 15 to 20 percent of the event’s total food and drink fee. You can avoid this unknown fee by asking up front. Once you get the proposed fee, add the service charge percentage so it’s already accounted for before the event. The last thing you want is to get hit with an unexpectedly huge bill that breaks the bank.
