I actually prefer it - I hate having the waiter hovering over me while i decide the tip + I can continue a conversation/finalize my bill at my leisure if my card is simply returned awaiting my signature.

In Europe they look the other way so you can type your PIN without them looking over your shoulder. Waiters are quite professional about this aspect.
