Is this murder?

So - the public transit collector was a huge asshole to my girlfriend this afternoon. She asked him to break a $1 coin into quarters so she could use it to pay the extra fare when changing zones, and he starts yelling at her and calling her stupid and telling her not to come back to get change again, etc... well after she got through the booth (I was just dropping her off), I was just shaking my head at the collector (I couldn't believe he was being a huge asshole about it). and he says,

"You can shake your head all you want." I was thinking about saying something earlier, but I hadn't figured out what to say, but responded with the first thing that came to my head,

"I guess you had a good day off on monday then." What happened on monday, is that 106 janitors and track workers were moved to the nightshift to make it easier/faster for them to do thier jobs, save money, etc... Well, they were pissed, and staged an illegal strike (including all the bus drivers and collectors), which shut down the whole public transit in toronto for pretty much the whole day (there was some service that started aroudn 6-7ish, but it wasn't completly restored until the next day.) They went sofar as to even kick people off of busses in the morning that they had already paid to be on (one of my friends got on a bus, and got one stop before she was kicked off with the rest of the passengers and the bus went out of service.) But the collector in the booth just got pissed, got a little red, and started yelling.

"I sit here for 16 hours everyday and work my ass off, I don't need people like you coming in here and giving me shit for how I do my job" It went on like that for a couple of seconds more, where I just smiled and put in a couple uh-huhs, and then just as he was getting madder (because my smile kept on getting bigger), I put my hands to my eyes and wiped away fake tears, while saying,

"Cry me a river buddy." Now most of the people waiting in line laughed at that, there was quite a crowd too since he had been neglecting his duties to yell at me some... But he didn't think it was funny at all - he totally lost it. Like spit on the glass of the booth yelling. I couldn't even make out what he was saying he was so furious he was mixing his words and not making any sense at all.

But my question lies here... He's an old guy, early 60's I imagine... And I figure he's the type just to keep on getting angry, especially the more and more I stay calm and smile... So - I'm guessing that he's getting on in his years, and that the anger isn't good for him - but could it kill him? Could I go back and get him angry enough to give him a heart attack? Noone fucking talks to my girlfriend like that and gets away with it. And if I did go and do that, would it be murder?

Jam it back in, in the dark.

That's not enough - he's got to learn not to fuck with us again.

There's nowhere I can't reach.

I could give a flying fuck what his life is like - it's none of my damned buisness, and it sure as hell doesn't give him the right to berate my girlfriend. If he had left his locked booth to continue yelling, I would have enjoyed beating him into a bloody mess.

Double Post:
And shit - that's true, I'm CPR qualified, so I'd have to help the fucker out.... But that might even be better - not only did I anger him to the point of heart attack, but he then would be in my debt for saving his life... haha! Maybe that mental stress would drive him to suicide.

Wait - I thought I was only legally responsible to help someone out only if I was on-shift (IE at school or work where they provide the training)... Not saying that I wouldn't help somone out if I was off-shift (except maybe this fucker).

How ya doing, buddy?

Not when it comes to my girlfriend, or any of my family for that matter. Noone talks to them like that. No one. If he hadn't been behind a bulletproof sheet of glass, then I would've pummeled him right there.

I am a dolphin, do you want me on your body?

I know - it would just be much more satisfying knowing that he would not do that again - not to my girlfriend, or anybody else.

I did get another kick in at him - I called the TTC customer service line, and told them about what happened. I asked them for a signed and written apology from the man to my girlfriend... They said it wouldn't be a problem at all, and took her name and my address. Now - if he's the type of person he seems to be - if his boss gets him soon enough (before he forgets about it), it'll blow his top

I was speaking idiomatically.
