Hey girls! I'm hoping to get some advice on this. I have seen quite a few venues and about half of them have had a service fee for the catering service on top of the tax. It specifically mentions that this is not a gratuity but a service/administration fee. So 20% fee plus another 7% tax plus another 20% for tip, thats almost 50% additional cost. Is this normal? I'm mainly concerned because I don't see every vendor charging it and I am not entirely sure when it applies.
