2 out of the 3 Wetherspoons near me have never stopped me from vaping. The only reason I dont know about the 3rd is because I dont go in there anyway.
My local, The Golden Horse Northampton, is ok with vaping. At 1 point the landlord was vaping to give up cigs, but he has since stopped vaping now as well. The landlady never smoked anyway. When I started vaping in there 1 other person started vaping a lookalike inside instead of going outside (she was already vaping before me) & since then about 10 of them have switched from smoking to vaping.
