I have two former roommates who are hairstylists and own their own salons. I lived with one of them through beauty school.They're both extremely social by nature, but neither one of them is particularly chatty with their clients. My one former roommate actually asks her clients just to relax and enjoy their champagne/beer/wine/coffee while the work gets done and she won't really respond if the client starts talking. She also has a waiting list pages and pages long because people mostly just want to talk; they don't necessarily need to have an actual conversation. I was so nervous for my first bartending shift, but then I learned that lesson. Just nod and smile and life should be just fine.
