Market Basket

I was at Market Basket on Bridge St Lowell, MA on April 17th at about 4:45PM. I was buying my groceries and the cashier and bagger were talking to talking to each other in an another language. (not English). They never acknowledged me. There was a couple behind me and I heard them say to each other. Are they talking about us? They are so rude. I am never going back to shop at that store again.
