What's the etiquette for reading the Metro on public transport in the morning?

Today on the tram I was sitting in one of the four-seater bits with three other people and ONE Metro. Two people left, including the Metro reader, and left the Metro on the seat. Immediately the cunt sitting next to me dived for the Metro, which was fair enough really because he'd got on before me. BUT he just rolled it up and put it in his bag!

MADNESS.

And the foxy ginger girl wasn't on today, which sucked.
