I will not take up for that Wal*Mart, but I do understand the frustrations on both sides of that coin. I also get my scripts done at one of our Wal*Marts and have been doing so for almost 10 years. I have not encountered the situation you have at all; everyone is polite and very competent. What makes the difference is, this Wal*Mart is located in an area of the upper middle class citizens, although their workforce does not come directly from this population, they do get some of them who are in this class, but mostly from the low to middle class individuals. Of course, they do get some real duds from time to time, but those are filtered out as quick as possible.
So, the point here is, not all Wal*Marts are the same. Their performance is based on the workforce that is available to them as employees. In this area I live in, I can show you some topnotch Wal*Mart Stores and I can show you several that are like the one in this thread. .....It is just like a Realtor will tell you: Location, location, location is everything when it comes to value.
