I Got in Free by Pretending I Had a Membership
“I did this at a local racquet club for awhile. The very first time, I walked in like I knew the people behind the desk. I waved and said a very friendly hello like I was happy to be seeing them again.
There was a guy and a girl working the desk and they both smiled and waved back as I walked in without paying or showing an ID card. Perhaps each thought I knew the other?
I did this on Monday nights for several months and it worked every time. After awhile, they DID recognize me and the smiles and hellos became genuine.” Story credit: Reddit / veggie_sorry
