Employee: Man those cookies look delicious!
Me: They are, I just made them from scratch! :D
Employee: Oh well I would love to have one!
Me: Oh sorry it's actually illegal in the state of Ohio to pass things INTO the drive-thru window, I don't want to get you into trouble!
Employee: No it's not I do it all the time!
Me: Yeah it is.
Employee: Can I have one?
Me: Sorry. No, I honestly don't want to share.
Employee: Oh well then I'll just spit in your food! Hahaha ( He says this with a big smile)
Me: That's not funny, like at all.
Employee: Oh? Why don't you think that's funny?
Me: Because it's not funny, go away and send someone else.
He left the window and the food runner handed us our food.
I was so pissed but in the moment I didn't say anything. I made my brother thoroughly check our food while he kept telling me to let it go. I listened to my brother and said nothing but it's really bugging me. My brother thinks I was over-reacting and wanted me to ignore the guy so I did. What would you guys have done?
TL;DR Employee acts unprofessional and then jokes about spitting in my food.
