Ari is like his brother, he doesn't have time or any patience for people who don't work and Meghan didn't work...we know she's lazy as all get out and I'm sure expected the WME staff to do all the stuff for her.
I'm sure there may have been a blow out between the two, Ari has a quick temper. I wouldn't be surprised if Meghan left without paying a dime that she owed. Her typical MO.
