I got my £20 note stuck in the zip of my purse (this happens all the time), but it torn a little bit of it! It's torn in a 'U' shape, but that part of the note is still there, just ripped a little!!
I'm just wondering if I can still use this in UK stores??
I've read a lot of different things "I have to send it to the Bank of England" "I have to go to my local bank" "I can use it if it's only 20%"

It's not that big of a rip, I would say 20%, or even less!
PLEASE HELP!!!!!!!!
