There are reasons that Sams Club and Walmart are at the bottom of the food chain when it comes to customers

Most people who decide they want to shop at a place it is the service they receive.  Walmart and Sams Club believe that you have a one size fit all approach.  Yes they do help find missing children but other than that.  You walk into any Sams Club, Walmart and Walmart Super center all built the same.  They do allow RV's to park for free.  Customer Service really stinks.  There neighbor Fred Meyer on the East Side is no better at this.  I have made more complaints over the years to that store customer service than anywhere else in Anchorage.  For Sams Club you would figure since members are paying to shop.  You would have a little courtesy.  I would recommend you head over to Lowes take some customer service cues.  When we are closed we nicely say we are closed at the entrance.  We do not yell it out to the customer in a rude fashion. Make sure that you also staff your people so when there is a rush you help the customers.  We at Lowes when the cashiers need help they help the people.  Walmart be like Lowes and help the customers please.  I may cancel my membership from your Sams Club we shall see.
