I worked with a guy last summer who doesn't exactly make a living from gambling as he already makes over £100k a year but probably makes about £30k a year from gambling. Obviously, he only makes this much from gambling as he has so much disposable income and regularly puts £5,000 on 1/5 shots. In fact, one time he lost £4,500 betting on Morton to beat Forfar at 2/9 (I told him it was a certainty!).
William Hills have cancelled his account as it "didn't kae business sense" for them to have him as a customer
