Chesty, your assumption is incorrect. I see no reason why a pilot landing at any airfield on a commercial job should be ostracised by a PPL just because he wears uniform as required by his employer.
However, I always choose to remove the bars from my woolly pully and my company tie as soon as the aircraft is tucked away back in the company hangar.
I have also seen some ridiculous examples of wearing inappropriate regalia. In particular, one chap obtained his PPL on Cessna 152s at one airfield then almost immediately joined a group owning a JP3A at a different one. He then took to turning up back at his old club, sporting an RAF Nomex flying suit with RAF style wings badge, the name "Jet Pilot" embroidered beneath AND still wearing a pair of leg restraints! He used to swagger about in the bar with the buckles click-clacking together. One day he butted into a conversation I was having and began telling us all about his brave exploits in the JP. My friend mentioned to him that I used to fly them for a living; he avoided me after that.
