Personally i avoid dealings like this cause it is not easy to trust a random stranger.
How about you?do you buy or sell bitcoins in person?If yes have you ever had any bad experiences?
Most police departments allow you to do exchanges of value there. Just call ahead and ask. Police want us to trade as safely as possible. If it's a large amount of value being traded, call ahead and ask for a time where an officer can be present to observe in case there are any shenanigans.
Also, its good to trade value at any public place in front of witnesses and cameras. At a mall security office, internet coffee shops, internet cafes, fast food restaurants, convenience store or gas station parking lots, big box retailer, etc.
