I seem to remember from a dim and distant life in the RAF, that we used to politley ask for "Fuel priority" if we were getting a bit short of gas.
Didnt use it very often as it was not the done thing, old boy! But as our normal landing fuel was 10 mins to tanks dry, when it was used it did indeed 'part the waves' - and cost the perpetrator an awful lot of beer at Happy Hour!
