My best and only bet ive ever made was when i got tickets off my sister to see Arsenal Vs Celtic in the champions league qualifier stage. I put a bet on Arsenal to win 3-0 and another on 3-1 - Arsenal were winning 3-0 but celtic scored last minute - Id put £10 on 7-1 and £5 on at 9-1 so i didnt win as much but was still happy with it. never been back to a bookies since - so im up from bookies (and casinos) in my life
