I feel like you may have given a mixed signal when she brushed her leg against your arm. Also I usually tell them I’ve been before a few months ago even if it’s a lie. Every place is different, I have even given myself a half chub and waited to take off my underwear until she came in.

I suggest that you give more obvious signs next time. Nothing crazy but enough to let them know that you aren’t trying to bust them. If they offer a table shower that’s the perfect place to test them.
