I know this may sound stupid, but I recently bought (actually my lovely husband bought it for me ) an Alma PM, and while I was out using it today it occurred to me that perhaps I should take the padlock off the zipper. Then I got wondering what others do with their padlocks? - take them off? or leave them on? I only have one other bag that came with one - it's a tiny bag (I don't know the name of it but it looks like a miniature Speedy in black multicolor) and the padlock just looked wrong left on so I took it off that bag. Also, I'm assuming that NOBODY would actually lock their bag - or do they?
