Sam Smith's pubs are different from most others anyway in that they only stock their own branded products, they don't have TV or music, and they are generally very cheap. They haven't allowed live music for about 15 years because the company refused on principle to pay for the new music licences introduced by 'New' Labour in 2003. I wrote in 2009 about the Plough, a large, multi-roomed pub in Whitby where I go every year for the folk festival: I don't understand a principle that turned the Plough from a large pub that was heaving during the 7 days of folk week with music sessions in 3 separate rooms and another in the large back yard, weather permitting, to one that looked almost deserted most of the time. Doesn't Sam Smith's want to make money?
Although those stupid music licences were scrapped in 2012, Sam Smith's still won't let the Plough reintroduce live music, not even unamplified. I bet the licensee looks enviously at the heaving pubs that do allow song and music sessions while he serves his half dozen customers.
As for swearing, I don't take too much notice except when people are loud and repetitive, at which point I find it irritating. I've occasionally heard people in my local, the Guest House, being told to cut it out when they go too far, and I'm quite happy about that level of control. While I find a pub full of swearing drinkers - usually male - off-putting, an outright ban does seem to be going too far.
That's Sam Smith's for you: they'd cut off their own nose to spite their face to make a point.
