Haha. I live near there in Cheltenham and have read quite a bit about the BP. Do people actually use it, what's the acceptance rate, and is it a good thing?
Well from what I heard, it helps keep money circulating within the economy. When you pay someone in BP you are in a sense investing in Bristol's continued vibrancy.
I very rarely see people using cash these days - so it's a lot of hassle to collect and process cash for a small % of customers that do use it.
