[/quote]We need to remember to look for the 51% signs just in case there has been a mistake made by TABC somewhere along the way, such as the charity theater mentioned in another thread (IIRC) that did not fill in their TABC application correctly and was legally 51% even if not physically so. But the above rule of thumb should work for most cases. Cops will probably go by it unless someone else complains to them about your pistol.
It doesn't matter if TABC made a mistake or not! It is not the CHL's responsibility to determine what the place should be. If a sign if there; NO GO! No sign; CARRY AWAY!
It is the business's responsibility to place the sign and the correct one! And they changed the law, and now it's defense for you if the wrong/no sign is there!
