@Cyth I don't know why people keep bringing up "binding contract." This is not a legal situation at all. It's called not being a jackass dipshit when someone does you a favor, and when you turn around and go against their wishes, you shouldn't be surprised one bit when they don't help you out further.
This dude knew very well the spirit of what was being conveyed to him. "If it's not illegal, it's ok" is social ineptitude. This has nothing to do with legality.
