The last supermarket I was in did that, but the arrows on the floor were almost the same color as the flooring so I didn't even realize they were there until I was just about ready to leave.
What stores need to do is get rid of those cardboard advertising display racks for specific products that clog the aisles and make it impossible for more than one person to get by them at a time.
And shoppers need to realize that if they have to stop to browse, they should move their cart to the side instead of parking it smack dab in the middle of the aisle.
And most of all, stores need to get rid of those damn beeping google-eyed robots.
What are these robots? I think that’s the second time I saw someone on FR mention them. I have never seen a robot in a store.
