World Gym ripped my friend off $60,000. Paid cash for unlimited lifetime membership. After one year, he missed one $1000 annual payment. They would not let him make the payment and killed his membership.
Same friend, joined Alexander Fitness for $40,000, 3 weeks before they shut their doors. They threw in great incentives like 20 free passes for friends, knowing the passes would be worthless in a few weeks.
There is no shortage of gym scams in Taiwan.
