I'm guilty of bringing fast food into FC. BBQ from MEM or BNA, Starbucks drinks, and food from airports with good fast food options, for example SEA and PDX, should be acceptable.
Keeping with the intent of the thread, You might be a Kettle with Medallion Status if:
1. You can't find the row numbers on A320 and A319 aircraft.
2. You think that Delta Airlines is the correct spelling.
3. You think that the only phone number for Delta is 1-800-221-1212.
4. You don't know what a redcoat is, let alone who is the redcoat at your home airport (smaller stations).
5. You think that Delta is the airline operating your CR2 flight.
6. You are surprised by the size of a CR2.
7. You are surprised by schedule changes even though you booked your flights 6 months out.
8. You are surprised when the college-age kid (or younger) skips by everyone in the general boarding lane and is later seen sitting in FC with PDB in hand.
