He is using the double technique. Where you order by more than one person and then use the first and best one. Then the people who have helped has actually wasted their time.
I have seen people do this with taxi firms, someone orders a taxi from two different taxi firms, and uses the first taxi that arrives. - May sound clever, but when you are blacklisted it can cause a lot of problems.
I'm aware of exactly what he was doing, fortunately I didn't do too much work.

P.S.: In all seriousness, this kid is attempting to market a sandwich effect that is totally.... "original". Good luck D;
