Did you know that the sale and use of marijuana is legal for medical purposes in California?
One of the things my musician daughter does for a living is to DJ where she lives in LA. She plays all kinds of venues, including a surprising number of retail outlets - clothes, shoes etc. And often they prefer to pay in kind, at least in part. Which, depending on the store, is usually fine. (You can see where this is going, can't you?)
Thinking clothes, daughter says, yeah, sure, that'd be fine.
"Do you have a doctor's prescription?" the guy on the phone asks.
Wondering what sort of place requires a doctor's prescription for its clothes, she asks carefully, "Er...prescription?"
Turns out that it is a pot shop.
"Don't worry," daughter assures me blithely. "I negotiated to be paid in drug money instead."
