There are so many business reasons that I could go into but I shouldn't have to.
~ the restaurant makes money by selling food... duh
~ the wait staff makes money by selling food... duh
~ it costs the restaurant money when you take longer to finish eating especially if you're not eating our food
~ the restaurant does not want to be associated with other business or your friends food.. it doesn't meet our standards that's why we don't sell aunt Cathy's cakes
~ it costs the restaurant money to serve the food, wash plates, and clean up the extra mess from the food you didn't buy from us.
Restaurants provide a service, a place to dine and visit with friends. We make money by SELLING food and drinks while you are here. If you don't want to buy our cakes or hors d'oeuvres why did you choose to come here?
