Scared of this man his real freaky !! help me??

That was a very good idea. Wise move. When you encounter people like this in the future, if you feel awkward and you want to leave. Just leave. Forget if it's rude because he's being rude to you. It's kinda like when you don't want to do something at home but your parents told you and if you say no you ume that they'll be angry. So you say yes. Don't be sucked in to this with strangers. You probably should tell your parents about this.
