What really galled me was the "a witness offered to refund my full price for my ticket as a courtesy to me." First, what the heck does he think Muxxy is? A not-witness? Secondly, the blockchain is a big old tattletale about where the money transfers came from. The other party says they bought the ticket, and the transfer record shows 425 Steem, which is a higher price than GMuxx was under contract to pay. I tend to believe the other party, and also that he had no clue he was purchasing a ticket from someone engaged in blatant breach of contract.
