I went to LA fitness too. I had just cancelled my membership at GoodLife and I wanted to try a new gym. When I went in, they gave me a hard time for trying to use my 7 day pass because they were worried I couldn't afford to work out there. They told me to "ask my mommy to get me a membership." I am 18 and I surely was a prospective customer before they talked down to me. Not impressed.
I gave the gym 4 stars because the facility is very very nice however.
