Deceptive Trade Practices Downtown?

So, you're running late for court and desperately looking for a parking place, and you come across this sign in front of a parking lot (which looks like it has been carpet bombed);

Your interpretation of the sign leads you to believe that:

A.  You can park at this lot for a flat fee of $5.
B.  You can buy the whole crappy lot for $5.
C.  You can park there for ten minutes for $5, but if you stay over an hour, it will be $15.

Well, if you guessed "C", you would be correct.  Sadly, I was running late and shelled out the additional $10 more than I expected rather than go look for another spot.

The non-apologetic parking lot attendant pointed out to me that the letters "MIN" are written above the dollar sign, so I should have known better.

As a side note, you may not want to park at the lot framed by Fannin, Preston, Prairie, and Main.  It's a rip off.
