I once heard a call from an pilot with a broad Scotish accent calling:
"routing from Fairoaks to Sevenoaks via Five Oaks"
...a tree spotter perhaps?
and heard of something in the lines of:
BA Pilot: Munich tower, Speedbird xxx request taxi for departure to LHR. .Tower: Speedbird xxx, hold at gate. .Lufthansa Pilot: Munich tower, Lufthansa xxx request taxi for departure to LHR. .Tower: Cleared taxi to runway via taxiways x,y,z. .BA: Tower, is this favouritism?. .Luft: Ve German pilots get up early in zee morninks & put our towels on zee runway.
I don't know if it's true, but I hope it is.
