Customer service...out the window?

OK, a little background--as I was checking out at the Sobeys grocery store the other night, all my checkout guy seemed to be interested in was having a conversation with an off duty employee who was behind me in line. His conversation started; his hands virtually stopped. After a few minutes of this I had a couple of words with the off duty employee, told the checkout guy to get moving and began to bag the groceries myself(he had had a problem with the customers in front of me and I'd been waiting long enough). As I'm loading my cart with bags, another cashier--supervisor I think--walks past the line of checkout counters dropping f-bombs left and right! I think I couldn't believe it. Then, as I'm exiting the store, she is standing outside the doors with other employees having her smoke break and cursing up a storm as customers are entering and exiting. Now, let me preface my query by saying that I have no real issue with social conversation or expletives having partaken in both on many many occasions, but while on duty at your job seems inappropriate and excessive. Now, on to my question: Is it just me, or does it seem that people just don't care about professionalism in the workplace anymore? Or are they unaware that other people in the general vicinity can hear them? Has customer service gone out the window?
