It's risky to pick up girls in Bristol. But if you get nicked by the police, you'll only have to pay a £200 fine and they'll give you a warning. It's embarrassing, but it's not that bad. I mean, you won't have a criminal record.
I think the best thing to do is to take the phone number of the girls you pick up, so after a while you will end up with quite a few numbers in your diary and you have to risk kerb crawling any longer.
