There are two in my area and both have the same problem: there will be a single non-pro bank of 8 self-checkout lanes, and then a bunch of empty lanes, one or two of which will have cashiers. Of the 8 self check-outs , one or two are always broken, so that leaves 6. Add in a bunch of large/heavy/bulky items that are hard to scan and now the line for self check-out is pushed back into the store, blocking multiple lanes and aisles. And as soon as you have certain items in your cart (molding/lumber by the LF, loose fasteners, etc.) you need an assistant to come help you anyway. Maybe it's just the customers in my stores, but it's just a terrible, slow, inefficient process.
