Early day faux-pas

I was told that there was almost nothing I could do that would upset the Shanghaiese. True to form, here are the first few faux-pas I've racked up in three days:

• Don't get into a taxi on the left hand side. Remember, like the rest of the world, Shanghai people drive on the right so you might get hit. (In fact they seem to drive on every side) And your driver will get irate
• When having a meal with others with lots of dishes, don't pick any of the dishes up
• Don't hang your umbrella on the seat infront of you on a bus
• Don't growl friendly-ly at a little kid who points at you in the street
• On Nanjing Road, there are people who collect empty plastic bottles from bins since they can sell them to recycling companies (big thumbs up, by the way) for a bitof money. If you have an empty bottle, don't give it to them directly and DON'T look at them. Instead put it nearby where they can get it themselves or they might think you're gloating (does anyone else thing this is so the wrong way round?!)
• On a similar vein, don't give fen (very small denomination, 15 fen is about a penny) to beggers. Wish I got a photo of the begger moaning at me! I didn't realise quite how worthless they were, my minder had to gve him a yuan to get him to go away!
• NEVER NEVER NEVER suggest to a visiting expert from the US who is chairman of one of the councils over here during a presentation that a 2 million tonne cut in carbon emissions (equivalent to the CO2 emissions of Scotland) from a single 1-kW solar panal might be unfesable (you could've trned the air conditioning off and we'd still have been cool for days...)
