I want to give credit where credit is due. In this case the customer[me] was tech wrong - but I learned a lesson, even at my age. I wagered on the WARK/ tennis match at Americas Bookie. Well he won first set, and led 3-0 in the second set , when the other player retired.It states clearly in their tennis rules that [they] grade these cases as no action. Well - I was under the impression that one set final was good enough in a best of three match. After talking with them they did a good thing and graded it as a win--some other shops have 1 set and win rule- So -- thinking of wagering on the first set only sometimes. Lesson learned and my thanks. gl all.
