I have a guy that has been helping me out when things get busy. I am considering using him more, especially for onsite call outs to my clients. He is a great guy, very intelligent and hardworking, we get along very well. But here is the problem, he is possibly the most insecure person I have ever met. He is very nervous around people, to the point where communication is sometimes problematic. He is ok around me, but customers freak him out.

I guess my concern is that his insecurity may cause problems regarding how clients perceive the business.

What are your thoughts?
