I work for a well known wax company that expects us to do fifteen minute BBW, and also additional services in that same fifteen minutes. I can do brazillians in 15, but I wish I had more time so I didn't have to rush people. However I don't own the Place and can't call the shots. I do think it's very funny that the instructor insists on 15 minute BBW but can't do one herself. Watch "the whole ball of wax" Give yourself some time and keep practicing. You'll get more confident, faster and more efficient.
