I know this is "Teaching your Grandma to suck eggs", but me and the Minister of War, have just been to Sok to get some shopping, and the bill came to 28 ytl. I paid on my card, and when I went to enter my PIN number, I noticed the assistant had put in 280 ytl as the amount. I pointed out the error, and she apologised, and amended it. I am not blaming her as this may have been a genuine mistake, but I wonder what would have happened if I hadnt spotted it, and left the store. So just a word of warning, to always check the amount when paying by card, as a mistake could be costly.
