I had heard that London is very expensive. When I landed there, after couple of hours, I went in a local chicken shop (as they call it, it's basically a fried chicken shop) to get something to eat. I gave the order and asked 'how much'? The guy on the counter said "Three forty nine" and I thought "Oh My God, London really is expensive man... A chicken burger for three hundred and forty-nine pounds." I said sorry, I did not bring the money and went out of the shop to stay hungry rather than spending 350 pounds on a chicken burger.
In China , we do not use hundred most of the times when we are telling the price. For example, if the price is 150, I would say one fifty rather than one hundred and fifty.
Later I discussed this with a friend and you can imagine what would have happened.
The burger was 3 pounds and 49p.
