I've watched the growth and transition of Walmart for many years. Back in the 1970's and 80's...when Sam Walton was running the show, Walmart was a different animal than it is today. Sam was Very concerned about his employees and treated them well. When he passed away in the early '90's, and turned the operation over to his spoiled kids, things began to go downhill. I made several trips down to Bentonville, AK., when I was working, to assist in major installations of new computers, etc., and it was not unusual for Sam to show up and ask if we needed anything....and he usually bought us lunch, and often joined us at the table. When he began to open the Supercenters, he often made a trip to the new store and greeted customers, and made sure that everything was going smoothly. Sam was not a pretentious person, and usually drove a basic Chevy sedan....but everywhere he went, there was a black Suburban SUV with blacked out windows...with 3 or 4 heavily armed bodyguards, following closely...after all, even back then, he was a billionaire.
Not long after he passed, the atmosphere began to change, and his billionaire kids all wanted even more billions. I have seen good Walmarts, and bad. Where we live, Walmart is the only major retailer within easy driving distance, and our store is well staffed, clean, and a good place to shop. However, I have been to stores in some of the larger towns and that is not always the case. Our store has only about 8 checkout lanes, and they are well staffed, and we can usually get in and out with little wait. However, I have seen some of the larger stores with 20+ checkout lanes...and only 5 or 6 open..even during busy times of the day. I'm sure the difference is due to the management, and when those at the top are only interested in how much more money they can make, management often will cut corners to make themselves look good to the headquarters and major stockholders.
Walmart, and many retailers, presently find themselves increasingly locked into the battle between "in store" sales, and "online". I fully expect the day to come when retail stores are a rarity. Amazon and Walmart are the largest consumer goods suppliers, and once common stores like Sears and KMart are quickly closing. Walmart has reduced the prices on many items substantially in the past year or so, to better compete with Amazon, and in many cases, they beat Amazon, already. With such a "price war" going on, customer service is going to suffer. How it all shakes out remains to be seen, but from what I've seen, I think Walmart will surpass Amazon in most cases. The days of having great customer service are over...unless you shop at some of the pricier stores...Macy's, etc....and those stores are quickly headed for the same fate as Sears. A few years from now...and very few...online sales will dominate retail, and the big shopping centers and large retail stores will mostly be abandoned, or converted to apartments, etc.
