Evangelizing to scammer

I’m selling a baby stroller on Facebook marketplace and this guy starts telling me how he’s gonna pay me with Zelle but needs my Zelle email, then I get an email saying I need to reimburse him some business account fee for the transfer. I had a feeling this was a scam from early on, but followed it in good faith to make sure. I thought you all would get a kick out of this conversation lol hopefully the seed planted here will take root!
