Kendall, I think the issue is the definition of "common" and the idea that these signs are "common". Jim has posited that 'No Travellers' signs are "common". The counter-argument isn't that this particular kind of discrimination towards Travellers doesn't exist at all, it's just how "common" these signs actually are.

I can't find 2012 figures for how many pubs there are in the UK, but given figures for the previous decade, I'd guess-timate there's around 50,000 pubs left. But how does "common" translate as a percentage of *anything*? Is it 10%? 5%? 2%?

I'd say that 1% of anything isn't really "common", but that would mean that now, in 2012, there's a 500 pubs in the UK currently displaying 'No Travellers' signs at any one time. Whilst I accept that discrimination, sadly, does exist towards Travellers, I genuinely find these kinds of figures hard to believe.
