Do you think a club will accept a photocopy of my passport as ID?

Hey, i'm going to an over 18 club tomorrow for one of my best friends birthday, although i am 18, two days ago i lost my purse with ALL my ID in it. The only form of ID i've got is my passport however my mum doesn't think its a good idea to bring that out, so do you think if i photocopied it, they'd accept it?
