For you yes.
Step back and ask yourself what a woman would do?
Yes all women are different, but answering some idiot yelling at you is not something most would do. Most walk around with blinders on.

Men are pigs. I start here and see is they prove me wrong.
I met my current boyfriend at walmart. He asked for my number.
I feel I should add I have lots of guy friends. Mostly SOs of friends and guys I play pool with. I have only had one of these guys ask for my number, yes the answer was no, he is a pig as he was the SO of a close friend.
A guy asking for your number is looking for one thing.
