"professional" is entirely about public image. If it's behind closed doors of course they no longer act professional. In some languages that value professionality there's even words built into the language. In Japanese there's the word "tatemae" 建て前 that translates roughly to "public position or attitude (as opposed to private thoughts)" that people hold while at work and they switch it off when leaving the work place/in private settings. Being professional is entirely about being a good lier.
