I just received my catering estimate and I was going over it and at the bottom is a service charge of 20% ($656.04) for my bill. It goes on to explain that this is NOT a gratuity and a gratuity is at our discretion. What the heck gives with this large service charge? They already nicked me for $250.00 for delivery, set up and pick up. I would like to know if anyone else was hit with this charge and what you did about it. Did you negotiate it out of the cost? Please help!!
