I wanted to say that

I was considering saying something to him, at the risk of starting a rumpus that would hold the train up even more than it already had been (damp tracks or something) when his mobile rang and he started mouthing off a stream of high-octane swearing at the person on the other end, oblivious to the fact that there were young children in the carriage. He seemed to think he was in a soundproof bubble, if he was thinking at all.

Everybody pretended not to notice, until a young mum said to him, "Oi, you ignorant little sod, mind your language in front of my kids. And get your bleedin' feet off the seat while you're about it!"

And he said, "Sorry, missus" and put his feet on the floor.

Now, what really annoys me about this is the fact that it had to be a woman. Before I became a grumpy old man, confronting oiks was a man's job, and people could be shamed into behaving themselves with a few well-chosen words, man to man. Now it seems as if only women are entitled to display any balls at all. AAAAARRRGGGGHHH!!!
