Exactly, nothing worse than actors running around and ruining other area's scares or just setting there texting. I have had a strict policy that does not allow actors to have cell phones and to take it one step further not to ever break character. If either one are done then they are asked to leave for the night.
Is it harsh? Some would say yes, but your haunt's success is dependent on the quality of the haunt.
Again, just my thoughts...
