What Are We Waiting For?

At Peet's Coffee a day or two ago, I asked an old man if he was in line, as I didn't want to accidentally skip ahead of him.

He answered me that "No, I'm waiting for Godot."

So I responded in deadpan with "You're probably going to be waiting for a very long time."

He didn't answer. I hope he at least appreciated that I got the reference. (In retrospect, I think a Petty-themed "The waiting is the hardest part." would have been better, but timing is everything when it comes to wit.)
