If you have ever worked in the service industry, it is very common for a restaurant to automatically factor in a 18% tip for groups of 8 or more. Groups of that size and larger tend to monopolize a waiter/waitress time more than if the waiter/waitress had 4 tables of 2. Also, if the restaurant management is worth their salt, the server will not be given other tables so they can concentrate more on the group of customers. Most servers make their living off of tips as their work wages are usually minimum wage. I think it is very selfish of the pastor to bring her congregation to a restaurant and stiff their waitress. I am sure that group had her running constantly. So, not only did she not get a tip for her probably excellent service, she didn't have other tables to make up for her time with this group.
Just my two cents...
