Curious Chugger Behavior

I had to pass through a chugging zone 4 times over a period of a few hours today. Each time, I saw the aggressive Greenpeace chugger. Except he wasn't in uniform or chugging. He was standing around doing an occasional little "chugger dance" but not seeking to engage with anyone. He looked quite depressed.

I didn't see any other chuggers for sure. There was a man with a rolled stripey umbrella who looked like he could have been a chugger striding away from the zone at around 1.05pm. So it's possible they were only doing a half-day but my friend just couldn't give up the street?
