Again... why me?

I was shopping today and shortly behind the cash stand there was something round with a cross on the floor. For a moment I was thinking of picking it up and handing it to the checker, but put it in my jacket pocket instead. On the way home I only had one thought:

"Why? Why?! WHY?! Why do I find something like this again?"

I don't even know where this is from or what for. Does anyone know? Write it to me in the comments.

I'm sorry for the bad quality of the picture. The shot was taken with my mobile phone.

Again something religious at a religious time. Just like around Easter with the statue and pendant. Crazy times.
