I handle difficult customer interactions by remaining calm, allowing the customer to express themselves, just making sure that I can do my best to supplement whatever they are trying to figure out or whatever they're trying to handle. But the main thing is just to remain calm when customers are upset because if you remain calm then eventually they'll calm down and you're able to help and assist them the best way that you know how or you're able to bring someone in that can assist them. But you just have to remain calm and just remember that sometimes people do have bad days and it's not anything personal towards you so you just have to remain calm and do your job.
