A couple of months ago, I was driving through Purcell, Oklahoma after dark and I noticed that I had a headlight out on my F250. I pulled into the local WM to get a replacement headlight and as I walked into the store, I noticed that it was extremely crowded and that they only had a single checkout counter that had a cashier. The rest were self-checkouts. I managed to find a replacement headlight bulb and then headed to the self-checkouts. I had left my wallet in my vehicle, but had a $20 bill in my pocket. After waiting about 10 minutes in the self-checkout line (the single checkout line with a live person was much longer), I managed to scan my headlight at the self-checkout and proceeded to pay.....only to find out that it did not accept cash!
Of the ten self-checkouts, only two of them accepted cash and I had to wait in line all over again.
Okay, I can see their plan to eliminated cashiers. But having their plan to eliminate cash sales really burned my buns that night.
