Free water and plastic bottles at petrol stations

A good tip here - many petrol stations throughout Thailand will give you  free bottle of water when you fill up with gasoline. BUT studies now show that the water in these plastic bottles (which are exposed to direct sunlight) is dangerous for you.

If you have any in your car throw them away of use the water to wash your feet after a day on the beach.

As I look at this photo of someone filling up I noticed that they are actually filling a water bottle up with gasoline and will soon be driving off on his motorbike - I think that this is pretty dangerous too - I wonder whether he smokes...
