A bit of an aside, the barber issue is interesting. I used to hate getting my hair cut because the social interaction was awkward. But when I became better off financially and had higher appearance requirements professionally, I started going to a high price salon. Other than the first trip, never felt anxious or like my social skills were lacking. That wasn't really due to me suddenly becoming better at conversation, it was due to the higher price salons hiring those with good communication skills. Likely this goes beyond just making clients feel comfortable but also is a good skill to have to understand what it is the client wants done to their hair.
