Would it be okay to refuse to give right-of-way on a sidewalk?
Why do you want to block the right-of-way on the sidewalk?
Just to see what happens. I just don't feel like it sometimes.
Everyone has an equal right to use the sidewalk, and you blocking it up just because you feel like it is wrong. You should follow general rules and let people pass.
I'm a special kind of person. I don't need to do what you tell me to.
The police won't consider you special if you are cutting people off and being a general nuisance in the eyes of the average person. I really think that you should reconsider doing this at all, because it could get you into trouble.
