Some random dude walked up to me while I was waiting outside a food place for my food and asked me this question.
I said “no, I dont give out random favors” and something along the lines of that’s sus.
Is it rude to say no to random dude that asks for a favor?
‘No.’ is a complete sentence and you do not have to justify yourself in any way. I don’t think that would be considered rude, either.
