Reminds me of a story I was told by one of the guys in BA unifrom stores...
A skipper walks in to replace his cap. He is handed one of the shelf and proceeds to put it in the carrier bag along with the rest of the replacement uniform.
The assistant asks "Excuse me sir, aren't you going to try it on?"
At which point the Captain remarks "oh, yes of course I should" and proceeds to put it under his arm and remarks "yes, that fits just fine!!!!"
