Of course not, but this anecdote from the Presidents Cup, recounted by Golf Digest's Mark Soltau, is an amusing reminder that not everyone knows who you are, even when you're Tiger Woods.
Early in the week, Woods ventured over to Stanford to speak to the golf team at the request of its coach Conrad Ray, Woods' old teammate at Stanford. Afterwards, they repaired to a local eatery, Lulu's, in Palo Alto, for lunch. When they were paying their bill, the waitress came up to Ray and asked him for his autograph.
Ray was perplexed and suggested that it wasn't his autograph she wanted. Turns out the cook had sent the waitress out to get an autograph and that the woman either did not know it was Tiger Woods or perhaps even was unaware of who Tiger Woods is and thought the cook had meant for her to get an autograph from the other guy, Ray.
