Well, of course there are more than 6. But this is just a start of the following things that could get you killed or maimed in London.
1. Jump the queue. Never do this. Queue=line.
2. Support the BNP (British National Party). They are racist.
3. Support UKIP (UK Independence Party). They have racist tendencies.
4. When waiting for the tube, don’t peer over the platform to watch the mice, yes, mice. You will fall head on into the oncoming train and will seriously interrupt everyone’s journey as well as get yourself killed.
5. Ask for ice.
6. Ask for iced tea.
Of course the above are all said with a bit truth, sarcasm and humour. Please don’t take it too seriously, or yourself mate. Cheers.
