I had a baffling thing at Tesco.
I take someone with health issues shopping and that's what we were doing. So, up and down the aisles we went and at one point a couple pushing a trolley said "Excuse me" which wasn't baffling in itself but what was was that I wasn't remotely in their way. It wasn't until later that I thought that they may have had some sort of vision impairment or some other physical thing... or something... which meant that I was somehow in their way although I couldn't really see how I was. You'd have to have been there. I suppose another explanation was that they were undertaking some sort of social experiment or just having a laugh. I'll never know.
It was just a baffling moment.
