I know that we criticise our ground staff from time to time; but I'm not sure that they have ever been guilty of anything like what happened in Bristol today when the match had to be abandoned.
From Cricinfo:
".. an issue with the covers being caught in the wind left the pitch exposed, before the three mobile covers came on from Ashley Down Road End. The tractor dragging the covers ended up driving down what would have been just outside the off stump of a right-hander batting from the Pavilion End. There was also a delay in closing the gaps between the covers allowing the rain to get onto the playing surface. Groundstaff then had to squeeze under the covers where they were passed mats to towel down the damaged areas at both ends."
