Actually didn't see the line about 100s of things employees have done. I'm guessing if it's stuff the employees have done and not just the overall store causing a nuisance by selling porn in a family neighborhood, the employees could be liable individually as well as the owner. Employees might have indemnity claims against the owner if what they were doing was within the course and scope of their job. But again, this isn't really my field and this isn't CA, so this is all just throwing out guesses and not actual legal advice.
What were you guys doing to customers??
