Let's face it guys, if you want a job nowadays you just NEED to have some experience, and if something like this comes along you just have to take it with both hands. I agree that maybe it isn't fair to have a non-paid intern, but that's how the job-system works. (in 'rich' Western countries at least)

To kaiser, I don't know how 'real' this hypothetical situation is, but I would at least give the intern a good recommendation if he did a fine job. I guess that's the least you can do. Maybe some Christmas discount, I don't know. Just let him know you appreciate him and give him something to help him succeed in life.
