I Had Free Access to the Gym For Three Years
“I used to be a member of NY sports club. It is a semi expensive gym here. At the time if you forgot your ID card you could just tell the person behind the desk your number. I always forgot.
After a while I noticed I was transposing two numbers in my ID and they were still letting me in. I cancelled my membership and had free all access gym membership for three years. Ha!” Story credit: Reddit / badamant
