Annoying thing is I think I know when I lost it but didnt realise at that point. I walked past some girl in the Crobar and she had some silly chain on that caught on my jacket and ended up attached to me, I gave it back, apologised and she swore at me, charming. I think that might have pulled the badge off.
Opposite end of the spectrum when I got the bus later two girls we're sitting in front of me, really hot eastern european girls, looked like lapdancers, one of their phones fell out of their pocket and landed by my feet. So I picked it up gave it back as she hadnt realised and got a total of three thankyous, a nice smile and unfortunatly no lapdance but maybe next time
