I want to clarify this by saying that I own a small catering company that was started by my husband, who had professional training and experience. We booked many events and he passed away unexpectedly. I am continuing the business as a part time venture with the help of his established staff. I have an event scheduled for next month at an art gallery and they are requiring us to pay a catering fee to the venue to cater there. Is this common? He is charging 12-20% of our bill to the customer. The customer was aware and didn't bring it to my attention at the time of booking. I have told the customer that I will not absorb the cost seeing how they were aware and neglected to inform me of the fee. I have 2 questions, is a venue fee common? And, how exactly would you proceed in the situation? The event is in 4 weeks. Thank you!
