Heard he took new memberships and collected Gym dues til the day the gym closed it's doors, without ever notifying anyone. People showed up to a closed gym.
I know a guy who rented his building from another gym owner , the other gym owner wanted the gym and building back
(bit more to the story but I cant be arsed)
He made an offer to buy the business back from him, he said OK
They had a date for handover and the guy in the gym sold everyone a Years membership for £100 each ( normally £200)
New guy took over and had to honour the memberships, first year in business had hardly any money over the counter.
