Personal space on TTC? Do some people need to be reminded of it?

At shepphard yonge the other day, I came to realize some folk need to be told off on the TTC. Have others experienced similar scenarios and how should they be handled?

A man was standing holding a wrist strap on the bus. For some reason he chose to stand sooooo far out of line the woman behind him, standing holding a wrist strap, was nearly pressing into the person seated infront of her and at somepoint couldnt balance. He, the one out of line, bent over twice for reason and each time bumped into her backside. Seeing how she holted each time it was clear he bunped into her butt. After the second bump she had to verbally ask this grown man to step forward, into his lane, so she could stand in hers. I was so confused on why he hadn't done so in the first place as he had plenty of room. This Is the second time I've seen this happen on the bus. Each time im lost on what I would do in such a situation.

Then on the subway, a woman sits beside me on the two seaters. Im in the window seat. She has her back to me and her hair is rubbing my arm. I scoot closer to the window as I HATE having a strangers hair on me. Time passes by and tell me why she collects her hair and brings it to her front. Im thinking, great! She realized her hair was too close to me! NOPE. She literally throws her ragedy hair at me! Im in disbelief. Couple seconds later she does it again! I had enough so i get up and sit elsewhere while being validated by a onlooker who shakes her head at her along with me. Another instance inwas seated on the outer seat on the subway and a man, holding the pole, had his elbow a couple centimeters from my head!

Any no-nonsense folk able to provide advice on how to handle these scenarios? What do you do when people are touching you, in your space, or just behaving rudely? Would it be rude to call them out? What if they ignore you?
