I went to a pub earlier with a 9game ind:e which had £10 in credit. At the time I didn't realise it but after I put my £2 in I had £12 credit, clicked Bullseye and won £3 then the barman came and told me that the £10 credit had been there since the morning. God knows why but I got a free tenner plus the fiver I won.
Why would anyone not collect a tenner of bank?
