I already wrote something else in here, but one other thought I had afterwards was related to IKEA carts -- they have four 360-degree casters, which makes them extra prone to just flying in literally any direction with a bit of wind if they're not returned to the corrals. Strangely enough, I rarely ever encounter an abandoned cart there, or full corrals; they're almost always empty! Curious if IKEA policy is far more rigorous than a grocery store on cart retrieval and return.
Last time I went to IKEA I couldn’t physically get the cart beyond the loading area. There were barricades setup that seemed sized specifically to stop carts from leaving the area.
As someone who went there alone, this was a real problem. The setup really assumes at least two people are showing up. One to wait with the purchased items, and another to get the car.
I’ve avoided IKEA because of this. I don’t know how to deal with it logistically.
Many people only use the carts to the loading area which has a well-patrolled corral next to it (any employee tasked with helping you load returns to the building with some or all of the carts).
The 360x4 casters are pretty insane the first time you realize it.
