Mycelium's Local Traders is awesome as usual, and I immediately re-bought the coins - I'm spreading coins, not divesting, after all. That said, parts of the conversation with the buyer:

"Can you guess what I'm using it for?" (buyer is female with heavy makeup)

"Well, kind of, but what you use it for is none my business"

Nods in what I can only assume to be appreciation

"You're such a nice guy. The other day I bought from a local and almost got robbed"

"Wow, that sucks. I'm definitely not robbing you, don't worry."

"Thanks."

"Now that I know you, can I wire you the money or Paypal it next time?"

"No"

10 minutes of explaining the difference between reversible and irreversible transactions ensue
