Tip 05: Stand on the right please
The escalators. One of the most useful inventions used on the tube (after the trains themselves of course).
On the London Underground these escalators, these moving steps, these exercise saving devices mostly come in groups of two or more. Generally, one down and one up.
In between these pairs of moving stairs, there are regularly spaced signs that simply state, "Keep to the right".
It's a simple message, straightforward to follow and yet frequently ignored.
There's a good reason for following its advice though. If you don't and you insist on standing on the left, perhaps to talk to your travelling companion, you will be shoved, bumped, knocked, coughed at (a favourite of tube travellers who'd like to get your attention without the trouble of speaking), tutted at and even on rare occasion asked to move.
Even worse than those offenders who stand to the left are those that stand to the right and leave their luggage on the left. Just don't do it.
