If I'm just getting a few things I will not hesitate to impose upon someone who is less 'height challenged' than I but for a full grocery shopping that's a lot of imposing since it seems the items I am most frequently looking for are both heavy and on the highest shelf. But when my list is long I will often send DH in pursuit of the high items while I and the cart collect the easier items.

What I'm still having a hard time with is people not understanding the arrows on the floor!
