I think I'm going to make a scene at McDonalds.
Why do you want to make a scene at a McDonald's?
I know very well that my actions are stupid but I want to be mean.
You shouldn't make a scene in a store because of how much of a lack of self-control it shows. Making a large scene makes you look like a child. You should behave while you are in public.
A manager slapped my mom because of something I did. I'm mad as crap.
This whole situation sounds absurd, but it goes to show that you shouldn't continue to make scenes in public.
