Players on-court habits

[Laury]

I found some habits that players have. If you remember some, please add it!

Serena always think that the court is a cat walk.
Sometimes Pierce always takes long time between points, she touch her hair, her outfit, took deep breath, etc etc.
Sharapova grunts
Schiavone's funny act when she challenge the calls.
Jankovic arguing the umpire.
Bartoli never bounces the ball
Davenport tying shoelaces at every change of ends
Steffi blowing on her fingers.
Monica Seles tapping the ground with her racquet on the return of serve
Conchita Martinez asking for the last ball she won a point with.
Sharapova often gives a look at opponent before serve.
Martina avoids walking on the court lines.

Maria Sharapova almost always tucks hair behind her ears before serving... even if there is nothing to tuck.

Monica Seles always adjusted her racquet strings between points.

Mary Pierce also blows on her fingers.
