Would have to be £5 extremes and WIYBS, as long as they weren't on dirty chips... In whitby i reckon i could turn £20 into £100 in a day if my life depended on it.
Remember driving to P'Boro one night a few years ago...opened the centre console as I was about to get out.... the 2 £100 Bags I realised where still sitting on my bed at home 25 miles away and I didn't carry bank cards lol that was a nice drive that night...
Best ever for me. Had a quid left (bfh) and a lad got 2 9s on a nudge on a cloud 9 and eft it. Decided to invest and ended up with circa 50 quid. Obviously that was years ago but it can be done.
