How to deal with Rude Customers in your Business?

It is best to stay calm, I have no problems of stress and had a lot of rude customers, from my experience, just do not want to be the cause to take it out on you, or are having a bad day.  

Relax

One thing is to help with stress is to do breathing exercises or yoga, which really help. if your at work, just go sit down close your eyes put your head between your knees and a 4 long, slow breaths will feel much better.
