Before I start, I'm not trying to start an argument, I'm just providing you with the information so that you've got some anecdotal stuff to consider.
Since new year, I've asked at least 7 (2 today) if they're boycotting and not one is. One of them goes from a pub in Darwen and doesn't know anyone from that pub who is boycotting. Nobody I've asked even seemed to consider it.
Maybe someone else has any info
