No employer would tolerate his learning curve. None. Why would an employer put up with a spastic tard who is nearly impossible to train when they have no shortage of non-smelly, non-retarded teenagers to do the same shit?
For instance, the Wendy's thing where he scared children with his terrifying Donald Duck impression. If he had a more patient employer who would have let that slide, but yelled at him for it, he would have learned only not to do that Donald Duck impression. He wouldn't learn not to be too creepy to interact with kids at all, much less not to do shit like that in public.
And that was just one of many retarded things that led up to him being fired.
With months of painstaking effort, an employer could get him to be marginally functional, but in the meantime, they'd be losing business and they'd have to assign tard wranglers to him, basically paying for two employees to cancel each other's efforts out, as the tard wrangler would be entirely occupied just dealing with Chris fucking up.
That's not employable by the Social Security definition.
