Back in '73 just out of RAF, Aztec passenger (the 'plane, not the passenger) insisted I have £5 tip. He was my only pax ever to offer so I guess it wasn't that common.
Had it been however and £5 then = £40 today, say two tips/day, five day week gives 40x2x5x50 = £20,000 Engross @ 40% = £33k Better than being an MP.
Of course the owners would then want pilots to pay for the privilege of operating their aircraft - but wait! Some do that anyway
