Sam's Club review: Customer service

We shop at Sams Club and Walmart. Twice now we approached an employee for assistance and was told by them that they don't speaks English. We walked away both times to look for someone that could help us. This is not a diversity complaint from us but a customer service complaint. Yes their is a diversified customer base but if you cannot answer customers questions when a majority of the customers speak English, that is a problem.
Additionally, I don't understand why we have to self check out when there are literally dozens of employees standing around on their phones or talking with each other. If you would take 3 or 4 of those employees and put them on a cash register, you would have some happier customers, especially among the old generations. There was only one cash register open and a long line at the self check out. We counted at least 6 employees standing around. Something is wrong.
