I, personally, cannot work in customer service due to my Autisticness. It stresses me out. Other people probably could, though. With most jobs, the problems are with ableism in how job interviews are carried out. The expectation to act completely neurotypical is really prevalent there, and normal Autistic traits are considered 'unfriendly' or 'suspicious'. There is no reason that would correlate to that person being bad for the job, but non-Autistic people are just like that.
