Transactions with only one possible next address?

[LordNacho]

I'm wondering if it's possible to create a transaction that the receiver can only send back to one specific place.

So for instance a supermarket cart would receive a coin, and the coin would always go back to the customer who put it in, after they return the cart to the queue. Currently this is done by a chain type system where one cart locks the next.

Transaction which can be sent to only one address does not make any sense. It isn't even a money.
It's essentially an asset in an escrow - you can use mulitisig addresses; the only way to "unlock a coin" is to get it signed by two parties and the party that gets it back wont sign anything that isn't coming back to it.

Problem is that nlocktime is not well supported or so I hear.

nlocktime is usable and could be utilized to create an offsetting transaction in advance.
It would be a similar scheme thane implemented in bitcoinj micropayment channel:
