We have worked Mr. May and his company. They honest people. Not rich. But, they have paid us.
Mr. May apparently a big fan of free labor. He has a nasty habit of not paying his employees. So I think it would be fair if after he has finished the job for you to return the favor! Maybe after he sees what it feels like to do a job and not get paid he can change his pathic ways.
Mr. May has a habit of not paying his workers their wages. So since he is a fan of free labor lets see when he does work for you if you can return the favor.
