Yo think that if you are going to stick a big neon sign over u our workshop door saying 'OPEN'...

[SaggyOldClothCatPuss]

Then it's probably sensible to turn it off when you are CLOSED?!
Im not overly bothered, but the garage next door has this. It is on constantly. Its quite bright at night and there are often people trying to access the place out of hours! Surely in terms of security and pissing people off, turning the thing off might be useful?

Maybe the "Not" sign above it is broken?

[SaggyOldClothCatPuss]

Nope. Its brand new. And completely pointless given that people have to do exactly what they would do without a sign, which is try the door and see if anyone is in!

Catapult and marbles.
Only effective response.
