Would you be upset?

This was posted on the door of an Arby’s it’s hard to read but it says

“Only well behaved children who can keep their food on their trays and their bottoms on their seats are welcome!if you can’t do this you will be asked to leave.”

Would you be upset or do you agree?

I personally think it’s their restaurant they can do what they want! And to be completely honest they have other guests to be concerned about as well and we all have to admit no one once to sit and eat with a bad ass kid running around and parents that act like they don’t see them
