I won about £400 on an accumulator a few years ago where all but one of the matches had either finished or already kicked off. I went in on a Saturday at around 2 on an FA Cup weekend where there were a few early kicks offs. So I put them on the quickslip and also a couple from the Friday. I thought i'd best put one 3 oclock in as well so I put Celtic at home against Inverness or someone like that. Put a £10 on the accumulator. I went in at 5ish (after Celtic scraped a 1-0 win) feeling more than a little sheepish, expecting to be rumbled. Anyway, the woman behind the counter noticed the Friday games straight away. But not the early Saturday games. She recalculated my return from a few grand to a few hundred quid, gave me the money and I made a speedy exit! A mate tried the same tactic the following round of fixtures but the bloke behind the till rumbled him when he went to collect. I haven't tried it since. Can't grumble at free money though!
