When I was a much younger walrus one of my school friends mother was having an open affair with a slimey toad of a guy so we decided to make him a cup of tea and put a dog turd in it.
Unfortunately as he was about to take his first drink from the cup the previously submerged turd popped up like a prehistoric log from a primordial soup and nearly poked him in the eye.
Of course he never drunk our potion and we had to make a very hasty exit.
Anyway I digress a little as what I am trying to say is that if you piss off someone anywhere (not just in Thailand) particularly in the food and beverage industry you may end up with more in your food or drink than is advertised on the menu ...
