While we have a keypad to the building, my office stays locked with a key. When I started 4 years ago I asked for a got a 2nd key to put on the key ring I wear on my bike clothes. 6 months later the locks were changed and even though I ask every 6 months I can't get a second key, so If I arrive before my office mate I have to dig into my backpack to get at the keys in my pants pocket. On the other hand, if I was interested in convenience, I'd drive every day.

Anyway, I'm glad no one took your wallet.
