I for one and glad John replied.

I do understand from a business mentality why he MIGHT feel like he does not owe anyone refunds. Even Trump cuts his losses and declares bankruptcy on one Corp while the others he owns thrive well enough to pay the debts of the bankrupt one.

While it is legal for Trump to do that, I personally do not feel that is the morally correct thing to do.

From a legal standpoint there are lots of variables here. Statute of limitations, was this business a sole proprietorships or LLC, were they investors or buyers, etc. etc. etc.
Only a lawyer/judge can sort those out so it will probably never happen over $275.

Morally, ethically and possibly legally I think John should pay the man his $275.

I hope he does because it will definitely have an effect on his and his company name if he does or does not.

Thank You John for at least telling your side of the story.
