"How to truly impress a client?" joke

I was in the airport VIP lounge, en route to Seattle, a couple of weeks ago. While in there, I noticed Bill Gates sitting comfortably in the corner enjoying a drink.
I was meeting a very important client who was also flying to Seattle, but she was running a little bit late.
Well, being a straight forward kind of guy, I approached the Microsoft chairman, introduced myself, and said, "Mr. Gates, I wonder if you would do me a favor."
"Yes?" he replied.
"I'm sitting right over there," pointing to my seat at the bar, "and I'm waiting on a very important client. when she arrives would you be so kind as to come walk by and just say, 'Hi Ray.'"
"Sure", he replied.
I shook his hand, thanked him and went back to my seat.
About ten minutes later, my client showed up. We ordered a drink and started to talk business.
A couple of minutes later, I felt a tap on my shoulder. It was Bill Gates.
"Hi Ray," he said.
I replied, "Get outa here, Gates, don't you see I'm in a meeting?"
