While I do agree completely he's trying to get freebies, IMO friendly truth is the best policy first, instead of this ban hammer crazy mentality. Tell him exactly why he's not getting a $200 skype, list his tips in total back to him and tell him you truly do appreciate the help but this is your livelihood and can't afford to give it away. If he's decent he will understand completely and still be part of the fun. MIght even turn into a nice tipper. If tho he gets pissed off or whatever, THEN go ahead and drop the hammer on him.
