The bet above was placed on Roger Federer to win Wimbledon a half an hour before the Wimbledon Mens final. Apparently the manageress called the office and asked if she could put the bet on, they confirmed she could and placed it with the price of 5/2.
However, the manager wrote ‘US Open’ as well as 5/2 (3.5).
When Federer won the match, Ladbrokes refused to pay out and cancelled the bet. Was this a deliberate mistake or a genuine mistake?
