This is something that really annoys me.  I just get used to where everything is, and then they move it!
They do it on purpose of course.  A manufacturer pays them or offers them a special deal if they’ll put their product at eye-level or in a more prominent place.
Or they do it so that I’ll be forced to go down aisles I don’t want to, to see new products that I’ve never seen before.  I don’t want them and I don’t need them - but they’re intent on thrusting them in front of me.
That’s why I prefer a smaller supermarket.  The space restriction means that it’s harder for things to be continually re-arranged.  I also like to be able to see the walls in a supermarket.  Some of these mega-stores are now so big that you can’t see the end of them!  I fear that I may never find my way out.
It seems that the argument about size is one about choice and convenience - but that’s a rant I’ll save for another day.
