Not likely. You’re looking at roughly £1,500 per door for the lock alone, then the “local council” markup, then the installation cost, maintenance, administration, and handling the cash.
If it costs £1,500 and you pay 20p, that 20p still helps, just not very much.
What’s the footfall of a typical bog? Say one punter a minute, over an eight-hour operating day, that’s ~£100 a day. You’ve paid for your £1,500 lock in just over a fortnight.
I’ve just made up those statistics, I’ve no idea, but I can see it adding up pretty quickly in busy areas.
Also, shouldn’t council tax pay for councilly things?
I’d say so, yes.
