As slf I couldn't give a dam about what the crew look like, smile at them they'll smile back.
They are after all the same as us in our work and don't like grumpy complaining arseholes, some people seem to think a ac is a hotel in the sky.
As a caveat to above ban all the prune faced been their done it old biddys who are trying to look attractive with trowel loads of makeup trying to hide their true sell by date, playing to the boys and trying to boost their ego.
Sad old trouts.
Its far better to look young and hungover than old and plastered.
