I was at a restaurant once and while waiting to be seated, I saw a lady who was wearing a QoS bracelet. As she was with others, and not knowing the situation, I stood next to her and made a comment about how busy the place was and then I interjected, "welcome to the family" She had this look of wonderment and then I said, "your bracelet" to which she said, thanks most don't know what it means. My comment was to be able to reverse the situation whereby one can see it on me and know what it means, hence the question.
