Re: a Landlord can deny you entry to his pub
At least in this country, the landlord can deny you entry on all sorts of trivial reasons, coz it's private property. I've been kicked out of enough offices and shopping centres for being barefoot to know. I rarely go to pubs, but the last two I tried, they wouldn't let me into the first one coz of being barefoot, the other one (being in a very barefoot friendly area) didn't even comment.
And no, health and safety, broken glass, are not valid excuses. I go barefoot for my own health and safety reasons, and when you walk around barefoot for a few decades, your feet get tough. Walking barefoot through broken glass doesn't even slow me down. I even have a medical certificate, which every one ignores.
As for offices, I guess it's well known that feral computer monitors will leap of desks and attack poor unsuspecting people, so wearing thongs (flip flops for non aussies) is suitable protection. It's OK, honest, I'm an experienced sysadmin and computer programmer, I can handle feral computer monitors in complete safety. Maybe this explains why some computer equipment is chained to the desk?
