Mirriam-Webster makes the point that while mute point is incorrect, it may be difficult to shut up (or mute) those who think otherwise.

My mom likes me to travel in uniform is that ok though?

Mother knows best, son.

If you’re walking around the terminal in civvies and a crew badge you’re a tool. Not buying the KCM, Airport discount, or JS excuse either. We have these things stitched into our shirts and pants known as pockets. The only thing you’ll get from me walking past you with your look at me badge is a blank stare and eye roll.

Strong this.

The ID serves very limited purposes in the order of their importance.

1. Discount on food, Duty Free items, hotels and sometimes ground transportation;
2. Scrape the ice off my windshield; and
3. To get through TSA/KCM

Now for what I really do:

Go in uniform through security ( foreign or domestic) so they won’t take my mayonnaise and hot sauce then do a Superman in the spazzie restroom, flash my ID to get my Starbucks discount then hide it again so I can drink for free come seat upgrade time.
I’ll flash it again to #3 if they Rosa Parked my ***.
I’ve depilotized my luggage so I don’t look like a baby seal fresh out of the Regional kiddie pool.
That’s ok with y’all?

Never had my condiments taken from my carry on anywhere, including London, and I carry it all.
