A few weeks ago I heard the following conversation on a busy departure frequency in the USA:
Delta Airlines Pilot: "Hey Houston, do you think we can fly a heading of 310 so I can have a look at my house?"
Houston Controller: "OK ... errr ... who was that calling?"
Delta Airlines Pilot: "Delta xxxx"
Houston Controller: "Yeah ... I guess so ... it should be OK ... I cant see a problem with that"
Delta Airlines Pilot: "Gee ... errr ... thanks a lot"
Houston Controller: "Yeah well ... that's OK"
