When I went to Japan for the first time I was supposed to ask a waitress for the check. I asked my Japanese girlfriend at that time what to say and she told me it's 'kimi to netai'. So, I asked the waitress and she blushed and didn't know what to say... I had actually told her 'I want to make love to you'...
Well, at least it was a nice way of saying it... 'bakku de shiyou' would have been worse
