The lock is for at work.
I don’t have a fixed desk, I work at multiple buildings, depending on rotation. So a small lock comes in handy. And especially this one, it’s light weight and with the 120mm extendable cord it’s perfect to lock it onto something. Just to avoid a quick grab-and-run.
Just the other day I saw a Strida-ridester at the station, but I was in a hurry to catch my train so no time to chitchat.
