Maybe it was the loud raucousness the concerned citizens objected to, rather than anything else?
Its unlikely, if you knew that part of L6 and its usual deadite street people - loud, leery, but cheerful would be a welcome change. The brothel was near the entrance to the road and down a dingey service alley to the scuzzy shops in the high street. (hence the need for the xmas lights at night.)
Personally i think the 'citizens' were probably fed up with the 24/7 coming and going of punters cars visiting the road. I think it was why that twat spiked my tyre.
I once had a smaller scale chinese brothel in my road, but the punters had to arrive on foot - its all double yellow lines. Never heard anyone complain about it - except the other residents in the brothels actual building.
But really i just wanted to support the O/P's ultra-cautiousness. There's just too many people with us punters in their sights. If there's any doubt - better to leg it and run away, you can always punt another day.
