That odd psychological phenomenon where people refuse to move beyond touching distance of the doorway, thus stopping other people getting on, while there's plenty of space further into the carriage/tram. Is it a phobia or are they just idiots?

2. Bikes on trains

Dear train-commuting cyclist, here's an idea: instead of wedging your bike by the train door, where it gets in the way of people getting on and off, usually cracking a few on the shin for good measure - why not just ride it to work instead?

3. People with backpacks...

Who refuse to take them off, then whack the people behind them in the face and pretend not to notice.

4. Taking up that extra seat

It takes an impressive amount of entitlement to put your bag on the seat next to you, but they're out there.

5. Manspreading

New York authorities waged a war on 'manspreading', and for good reason! As the campaign pleaded: "Dude, stop the spread please. It's a space issue".

6. Myki fumblers

Don't start rummaging through your bag for your myki while blocking the train station barriers or tram doorway . Have it ready to touch on. Easy!

7. Leaky headphones

Do they really not know we can hear their terrible music? Or do they just not care? (Poster from Tokyo Metro.)

Oh. And don't be this guy…
