Bob, those coppers over there with their ubiquitous CCTV on street corners around pubs and such are way ahead of us.
Here in the STates, a lot of folks are up in arms about using CCTV to monitor street happenings, citing big brother watching us. Would they ever howl if we told them to remove their chapeaus...
I wouldn't be at all appalled if those two dapper men showed up inside the grill room of my golf course with cap in place, expecting some wry old tales from a couple of good old gents.
On the other hand, this guy wouldn't be welcome at all, even if a hood isn't exactly a cap... no doubt he isn't planning on being around the club or on CCTV
