Silly hat syndrome
A while ago I wrote about inappropriate use of puns in business names- a silly name for a cafe or hairdressers is one thing, but cause for concern at a doctor's surgery.
To this rule, we can add the wearing of silly hats. Being holiday time, people love to wear all sorts of silly christmas costumes, just in case the hordes of shoppers and grating carols hadn't tipped you off that it was the festive season. And mostly this is fine, at least if you are making coffee or working at a checkout. But you can understand my alarm when, boarding a flight on our national carrier, I catch glimpse of the pilot seated in the cockpit decked out in reindeer antlers and a red nose.
Rule of thumb: serving drinks and handing out in flight snacks = good to go with the santa hat. Flying a commercial airliner at 500km/h = stick with the captain's uniform.
