/qa2/ - Business Inquiries

Hi /qa2/. My Business Inquiry is as follows: I manage a fancy local restaurant that has been completely booked out next week for a rich customer and his friends next week. This customer is known for being disruptive, so much so that he has been kicked out of 109 other restaurants for his bad behavior. Should I take this customers money to the detriments of my regulars or should I refuse him and maintain my integrity?
