Hey hey, calm down calm down!
Stop getting your knickers in a twist. Could have been better written, granted but if you read the uniform booklet all is explained.
Buy your costa if you must, drink it in situ, seated, hats off obviously or take it to said mode of transport and drink it there, hats
and ties off. Hardly rocket science and hardly worth getting worked up over.
Unfortunately, there are a growing minority out there who require these basic reminders, like those that insist on wearing their flag of nationality on the jacket, enough bracelets to adorn a gypsy bare knuckle fighter and the increasing number who don't wear a watch. When you've been flying 3 years and not one person has told you that a watch is mandatory, then some blame must be placed with the Captains too.
