Hang on a minute Tex and 411A, here is a London ATCer - among the best and busiest in the world - merely trying to find out why he was required to control an ac which would have been better off on the ground. If there was more to it, as wino suggests, then surely the crew owed ATC some clarification. This is just the sort of traffic which can lead to congestion and, therefore, flow control restrictions.
On a similar theme, I get seriously p**ssed off when, coming back to LGW at the speed of heat just before 0600L, with a night r/w slot, I find the airspace clogged up with the world's favourite airline's 74s and 77s slowing down and whingeing about not having night slots, thereby denying me, and all the others like me, the use of our night slots. Land and take the hit or manage your flight better guys.
