I actually do not have a wallet and carry my cc and other cards as well as my cash in my pockets...
When I had a wallet I lost it several times and now I don't have one I occasionally lose a id card or some other important stuff, also way too much money has fallen out of my pocket...
I never lost mine, not even when I walked around seedy parts of Hong Kong in search of cool video games to buy, or sitting down in seedy parts of Hong Kong playing Ketsui... and I kept my wallet in my back pocket too despite many people's recommendations against it..
I actually lost mine once.....the apartment mantaince guys found it in the garbage a week later. I was glad to have it back but pissed off as well because the $300 I had in it was GONE!!!
I wanna find the bastard who took my money and strangle him!!
