What can I buy with him "saying he will return the money"? Until he returns it, he is stealing. No one agreed to loan him money
Different scenario
He collected 300k
That 300k went to Nigeria
Is it titled as stealing ? Yes he owes the money
But you’re saying every business transaction that doesn’t turn into a profit is stealing.
Does he have the money now ? How was he going to pay the hotel to honor the contract ?
