Being from the old security conscious days I still avoid wearing uniform in public where possible. From a privacy point of view I wouldn't wish to publicly advertise which organization I work for; this would be the same if I worked for any other large and recognizable organization. However, if you do choose to wear uniform and public (and no reason why you shouldn't if you wish) then at least adhere to the uniform regulations and think about the image you portray. Wearing the Queen's uniform is an honour and should be regarded as such. If you see someone not dressed correctly then pull them up and correct the matter. Isn't this called discipline?
