Seen in a supermarket car park

I had to look at their website to see what this about and I will be honest I’m still not completely sure.

It seems to be about returning unwanted items that have been bought on-line BUT what attracted my attention was there was someone using it and he appeared to be collecting parcels. So it must be for collecting as well.

It looked like a game as different doors opened to access the parcels,.

I suppose it is not very high but I can imagine someone having to ask a taller passerby for help.
