Fast Exit

Won a prize for a meal for two uptown tonight so off we went. Handed over the ticket to the waitress and had our meal and drinks, waitress never reappeared ( in fact no-one really bothered us again) so once finished, got up and left.
Got about 50 metres down the street when we heard the footsteps and the shout Oi! you've not paid you're bill. Turned out the waitress hadn't passed on the fact we had a voucher before clocking off.
