Cursing is not a sign of immaturity. In fact, it's the opposite, as those are considered adult words that adults use regularly. Also, having worked for Walmart for a number of years, he is in no way wrong to have said it, IMO, and I agree with his choice of curse words as well. Walmart has earned it from every employee they have ever had. Besides, Walmart is doing what he suggests and effing everyone all the time, everywhere they exist, always.

@Jolanta He could have left out the swearing, but he only used it moderately, so he was only usign it for emphasis in what he was saying. I think judicial use of swear words shows maturity as opoosed to using them in virtually evry sentence.
