Wow this was hard to follow, bottom line if you never agreed to pay him for anything then you dont owe him anything. If there is an agreement to reimburse him for the bugs then you owe him, but for 10 bucks it sounds like either a the guy is having really hard times and 10 dollars means the difference between eatting that night or not. If that is the case he has worse issues then 10 bucks can solve. Or he has nothing more exciting going on in his life then to harass someone. Go to the dating site and help him find a match maybe they will entertain him LOL
