Miscommunications

During my visit to John Lewis (the British version of an upscale Target) to buy sheets and pillows, I had my first huh? moment when someone was speaking to me in English. I was carrying a bunch of things in a basket and my arms were in a lot of pain. A male store employee came up to me and here is how our conversation went: 

Man: You know that basket has wills. 

Me: (looking at him quizzically) What?

Man: It has wills. 

Me: Excuse me? 

(Repeat above exchange a few more times)

Man: Here. 

He took my basket, put it on the ground, pulled a handlebar up from the side, and dragged it along demonstrating the utility of the WHEELS. 

Me: (said while incredibly red in the face) Ohhhhhh. Thanks! 

I seriously thought he was telling me that the basket had a will of its own and that I should be careful not to let it run away.
