Pathetic! Walmart, not you.
I had the business and was constantly turning customers away because they came in after we had a full schedule for the day or we drop dead HAD to close exactly at 2000h. If I had a full staff, a training budget, and was able to stay open all night (There were no other all night service operations for 40 miles) Then it would be a money maker. As it is The TLE looses efficiency but the customers have a lot of time to wander the store and possibly buy a ten dollar item rather that 500 bucks worth of tires.
