why cafe and resturnats do not allow out side food in their place

Why can you not bring out side food in some else restaurant? Well the first reason it rude. Now I know some people who go to the book store cafe or a fast food restaurant is a super store. Here why the cafe and restruants will not let you bring your own food in beside being rude it all so a board of health rule. Most restaurant even if they did not cook the food there always a possible of food contamions like Salmonella bacteria this is a form of food poisoning . Say some bought out side food in and ate it then got the food poisoning that cafe still can get sue no joke this why most restaurants, cafes will not let food in yes some time the restruant and cafe is to busy to notice that some is eating out side food.How ski lodges cafe since the cafe is kind of a separate eating area the food business has nothing to worry about. Now let for get about the board of health rule. If you own a restaurant would you want people to bring out side food and drinks in to your place? I say no If I had my own building of a restruant I would want people to buy from me that how the restaurant and cafe make money. This why I starting with a food cart first then work my way to a deli one step at a time. So if you plan to go out to eat here what you and your date should do look on line of the restaurant that you are going to eat make sure they sell food you like by looking on the on line menu plus this can save time this way the lady will have more time to make up her mind we know how long that takes lol ok that it for now.
