When Patience is no longer a virtue

HAH!!!!! Don't get me wrong! I am very much aware that I'm in the service-oriented environment. I must always bear in my mind that patience is virtue when it comes to dealing with unreasonable, difficult, and they-believe-to-be-gods clients. But, sometimes, these so-called superior beings need to be pulled down from their self-erected pedestal and give them a tongue-lashing they WILL NEVER FORGET AS LONG AS THEY LIVE!
