I was on a bus in college when there were no seats available. And sadly, not even pole for me to grab onto, just the over head hand grips. Remember, I am short, 5'1" - I could reach it, but it provided no stability because I was on my tip toes. Men sat all around me, watched me struggle, and not one offered a seat. Of course on a sharp turn, I fell into one of the guys. He asked, "are you drunk?" and that sparked a sharp, "No, I am just short look at me on my tiptoes! I can barely reach it!!" Do you think one of them offered a seat after that?
You'd be incorrect if you you said yes.
