Some people term the West Indies to be courteous, sincere, honest, etc. Please note that in the 5th Day's play against South Africa, West Indies and the umpires (includes simon tauffel) played a great part of their honesty. Amla;s catch gymnastically taken by Gayle (that's what they claim) was of a no ball and no one noticed it. Secondly, Smith's catch taken by Gayle in second slip was grassed by Gayle in similar fashion of Michael Clarke's however, it was given out and no one went inside this sh1t.
In fact, least anyone bothered about these instances, as South Africa were cruising towards a solid victory and relied on the other batsmen to come for their rescue. West Indies enjoyed their slice of luck as any wicket that had come in their way was a jackpot for themselves!!
