The same as I do now probably.
I don’t give people credit for being rude just because they avoid foul language.

Let me rephrase my previous point: you were being a bloody cunt. Maybe you’re a great lad normally, but both your replies to the other guy were cunty.

Try to be nicer to people. This is probably not the first time in your life a stranger has reacted to your behaviour.
Do better.

Man there’s not much that annoys me more than someone being an asshole, and then being upset when people are assholes back to them.
