As I needed new batteries I went to a supermarket and what can you do when you are alone?
First I hoped to see a couple, one of them waiting outside while the othe would go in, but there was no. So I took my bike cover.

Unfortunately also my camera was undercover, so I have to illustrate it by archive material. Additionally, I used my bike lock, but in this case with alarm. I came back soon and of course nothing had happened. But I knew something would happen soon, so I held my key ready when I carefully removed the cover. But not careful enough, because the alarm started (it is sensitive to vibration). With the key at hand I could end he alarm before it really became loud. If I would have to leave the bike for longer I additionally could fix the cover with 2 locks, but then I would have to be planful with the alarmlock to be able to nlock it first when I come back.
I wonder when I will be in such a situation of next level security demands. And still I wouldn’t go to a museum or so with my bike well locked but the all the bags more or less protected only by cloth and some noise if the alarm rings.
Would this stop a determined thief who is willing to take stuff out from a bike in public? And this public – I know some people are courageous, but are always the right people at the right place?
