Last year I asked Denise Capriati for a photo. She looked completely confused by what I was saying asking. So I ended up having to wave my camera under her nose and saying "photo?" quite loudly at her. Once she understood, and I'd taken the photo, I said "say well done to Jennifer for winning her match" which again she couldn't understand, so I ended up repeating it twice. And then just giving up and saying "thanks".
And then, not a player but a ref, we spotted Sandra De Jenkin. So I chased after her and asked if I could take a photo, and she was like "no, no, get the players" so I ended up whining "but you're my favourite umpire, remember Australian Open 2002 final"
at which point I think she decided I was insane, and it was probably safer just to let me take the photo.
There were a bunch of kids at Wimbledon this year who clearly didn't have a clue who anyone was, and were randomly chasing anyone who even vaguely looked like a player for their autograph.... And ended up asking Vivi's coach/friend for theirs. I think they felt sorry for it, and so gave him Vivi's towel.
And again, there was some random woman chasing after Cara Black who just kept saying "Cara, Cara, Cara, Cara" right in her face. Dunno whatever the hell for.
And the best til last. Not actually said to a player, but it needs to be mentioned. I'm standing there watching Martina Navratilova practicing with Lisa Raymond. And this woman's standing next to me complaining that Martina doesn't transfer her weight correctly on her serve, "look look" she pointed out to her partner. And that this year she was playing with LUCY
It took a lot to retrain myself from hitting her with my baguette.
