Thank you for a thoughtful and interesting reply.

The public health angle is interesting. I know noise pollution has a measurable negative effect on quality of life.

I bet making the signs bigger would actually have some effect in that it would socialise the message to control volume to the public in general.

I suppose I don’t mind quiet conversations taking place but when I can hear it from five rows down it grinds my gears.

Been better lately about getting up and moving when someone comes in and sits down making noise but I sometimes need to go two three cars to get away from that.

Anyway cheers
