I always have a way of dealing with arrogant and people that thinks their crap don't stink. I will yell at their face right in the store in front of all the customers where the arrogant people will just shut up, surprised and end up listening to you, then at the end I always the one that's right and they're wrong and 99.99% of the time they beg to apologize to me. As a customer no one wins over me.
