Were these McDonald's employees just joking around or being unprofessional?

My aunt and I went to McDonald's, and the staff seemed distracted, joking around and making us repeat the order a few times. One of the workers, a young guy, kept smirking and laughing with his coworkers while taking our order. After we paid, he shouted to another worker to finish it, still joking around. There was also some mention of getting "her" Instagram. Was this just typical behavior from young employees, or did they cross a line with their unprofessionalism?
