Actual conversation at my register:
Customer (probably mid 60s): Am I old enough?
Me (totally confused): What??
Customer: You looked at me like you were checking my age. Am I old enough to buy bananas?
Me: It's a little different with bananas. I was checking to see if you were young enough to buy bananas that are this green.
I love it when my mouth is faster than my brain :nod
