I went shopping 2 days ago.... yep, aisle blocked by two women chatting.

The local grocery stores I go to have decided that 'some' lost or damaged carts are preferable to expensive locking systems.... and 'most' people return the carts to outside storage spots scattered about the parking lots. Very few carts are taken off the lots, as it is just too far for most to walk home. I do see carts in large shopping centers abandoned WAY at the other end from their home store... I suppose those employees who work till closing have to collect them.
