Was fairly late in the evening at LL many years ago and only a couple of A/C on the GMC frequency:
GMC: "UALXXX give way to the Pakistan 747, you're then cleared in" (to the cul de sac)
UALXXX: " Roger, after the Pa*i"
There then followed a pause to which the Pakistan replied " We're not moving until we get an apology!"
UALXXX: In a very confused voice " Err.. Have we offended you sir? Well, we're sorry"
The UAL had obviously just abbreviated the C/S and had no idea what he had said!
The Pakistan pilot was obviously very upset as he then crossed a Red stop bar, and then proceeded to cross an active runway ending up in T4 for a departure off 27R!!
