Indicative planning Puns

(x-post from /r/TalesFromRetail)
[was told I should post it here as well]

This happened shortly after I started back to work in retail.

My grocery shift had just started and I was about to begin facing one end of an aisle when I spotted a man in his mid to late 30s at the other end of the aisle. We made eye contact and he made a beeline straight for me.

Me: "Hi. How are you today?"
Him: "Do you know what to do if you get a sudden urge to strip off all your clothes and run around naked in public?"

Now, at this moment, I'm not sure what's happening. I can't pick up any clues from his body language that would indicate where this conversation is going to go. I'm a wee bit concerned that this man is about to start taking off his clothes in front of me. Not exactly what I had planned for the day. He's staring at me intently, waiting for a reply. I don't want to spook him, so I do the only thing I can think of and that's just to stand there and stare at him silently.

After a few seconds, he says to me "Just spray yourself down with Windex. It prevents streaking. Have a nice day!"

He grins and walks away. I started laughing (a little too hysterically ... mostly because of relief).
