No. 1 - Burlesque vs. Stripping
There can be a fine line between a burlesque performance and a strip tease. Burlesque usually involves songs, more interesting costumes, maybe a dance routine, and possibly some nudity. Stripping involves some of that, just a little more down and dirty.
Now Porsha was OK with a little Christina Aguilera/Cher-style burlesque, but a strip club was not for her. So when the girls rolled up to the club, she was none to pleased at what she saw. Porsha accused Phaedra of misleading her about the fact that it was a strip club, and I can't help but wonder what would have happened if they had gotten her inside and then she realized it was a strip club. Would she have stayed or freaked out and left?
