Bournemouth has a large square in the centre of town, it has become a general meeting place and an area for various markets and sellers of cr*p. It's also become a centre for people who play instruments, even small bands with the aid of a large amplifier. This sometimes happens between opposing bands so you can imagine the cacophony of noise that ensues. We have a road that leads up to other shops, pedestrianised of course, there is often some sort of music there. If one is foolish enough to go into town on a Saturday the noise can be deafening. I've been told all this is illegal but I've yet to see any of them moved on.
This is a huge pet peeve. BTW the doggy doo bags placed in trees etc, a friend of mine claims she does this to collect the item on the way home - which she does - she also says there is often not a bin to put them in and she doesn't wish to go on a long walk carrying said poo.
