A reasonable bet at the price I’d say. Unlikely as you note but stranger things have happened.
It does seem a bit odd to be going after betting shops, as you say they will take care of themselves to some extent. There never seems to be that many people in them any more.
I do agree about those slot machine centres though, they are awful. No skill, just mindless button pressing with the long term odds stacked against you and they don’t even have to turf you out of the 24 hour ones.
