Personally, it's a tie between The Pepper Spray Incident and the way Chris treats his pets.
For PSI, it's like . . . yes, I know the employee
thankfully didn't get the brunt of it, but using mace on a person that had absolutely nothing to do with the design of a video game character is just a level of autism that I can't begin to comprehend.
Pets are hopefully self explanatory. For fucks sake Charb, take them out for a walk or change their diet. Just something other than leaving them to rot away in the house.
