LOL! Check out this corporate guru's advice (pay attention, he makes $20k/gig). Here's a testimonial from a satisfied customer:
"I have integrated many of his views and especially the idea of not saying or writing "No problem" or " That wasn't hard to do, it took no time at all"What I now say or write is "That was my pleasure, glad to be of help. I know you will return the favour someday."
