What Would You Do?

How much money did he give you? I always try to work with people, because I don't really have any limitations on storage. But if you're waiting for the rest of your money (which is what I'm assuming) I would start laying down a deadline to him.......and maybe mentioning his "non-refundable" deposit. I try to be flexible with people if I think they are on the level with their reasons for not picking their stuff up; I know it can be overwhelming traveling 100's of miles.
