I don't know what you might call them in your part of the world but in my hood we have these little frozen drinks called slushs aka slushies.
You put a few squirts of dye in a cup and fill it with sugary ice water, kids love it.
This adult client comes up the ticket register, buys two tickets, makes a bad joke and while I am trying to hand him his tickets he starts french kissing his girlfriend RIGHT IN FRONT OF ME.
I awkwardly look away until he takes his tickets and heads to the concession register right beside.
He orders a medium slush and asks if we can put all 6 flavors in it. I tell him only two flavors are recommended in a medium slush and he looks me dead in the eye and says:
"I am thirty-nine years old, i can manage my own slush!"
I simply could not argue with such a flawless statement.
