I think you should try this

This is something that somebody did to me here recently. I am not sure if it will work for him or not but maybe it will work for you. Say go into a restaurant and bar and order steaks, beers, shots and whatever else you want. Then because the owner did not sit down at the table with you, when your bill comes pay half and say that this is all you think you owe. See if that works for you. That is how someone reacted to their bill, I am sure their reaction to someone doing that to them would not be a pleasant one.
