And the woman in front of me puts what is clearly a thermal bag of crustaceans into the plastic scanner bin thingy ...
Traveler: yes.
Agent: How many?
Traveler: 3
Agent [still deadpan]: I'm very sorry ma'am - regulations are that you can only travel with crustaceans in even numbers.
Traveler: uh - what?
Traveler: Uh
Agent: I'm afraid you'll have to go back out and ....
Traveler: ...
Agent: Wow, the line is long.
Traveler: But ....
Agent: Even numbers, ma'am.
Traveler: But ...
Just pull one out and give it to me.
Traveler, dazed, is fully unzipping the cooler bag before he's like - LADY, I'M KIDDING.
