The FBO is Signature; I stopped (place was fairly empty, there was only
one
other plane there that was not tied down), went in, looked at the weather
terminal, called FSS, and went back to the door. Surprise! It was
locked.
I pressed buttons, nothing. Then a lady came to the counter and informed
me
there was a $22 fee for coming there and I could leave as soon as I paid
it.

Most places that's called "unlawful detention".
