A guy walks into a restaurant. Half an hour later the waiter hands him a bill. The guy immediately says:
"102004180"
The waiter being a rather smart chap, waitering only because of the recession, immediately understood what he meant... but do you?
If the waiter is such a "smart chap", why does he present a bill to someone who has not eaten anything. I have another solution that might also work:
I ought to owe over 1.80. (Over = O+FOUR)
