Jim, I'm not sure how much clearer I can put it. I find wholesale discrimination pretty bewildering. My politics are left wing. I'm anything but racist. I've been a member of the Anti-Nazi League in the past and have gone toe-to-toe with right wing boneheads in my youth more times than I care to remember. My better half is the daughter of East European immigrants. I'm not sure what else to say really. Why the hell I'm explaining half of this to satisfy a stranger on the internet, I don't know.

However, the fact remains, I've genuinely not seen one of these signs and I'm not aware of anyone in my social circle having seen one (it would have been a talking point and probably a reason to even leave the pub in the first place).

Also, given you've not seen one yourself since 2005 - that's a full 7 years - either you've stopped drinking in pubs or perhaps they're not really as common (now) as you've claimed. I'm not denying these things have never existed, and I've not said anything that could be reasonably interpreted as such, all I've queried is how 'common' they actually are.
