Kneeling Down

Sometimes while I am working I see a waiter or waitress kneel down to speak with the guest at eye level and take the order.

I personally couldn't do this cause I would have a hard time standing up afterwards and after only a couple of times my back would begin to ache. I am wondering though if this kneeling down by the table to speak to the guest adds much in the way of the personal touch or is it a little too much. One time I use to work in this restaurant where the waiter use to actually pull up a chair and sit down and chat with the guest while mentioning the features and taking the order. We eventually scrapped the idea.

From two points of view , one do you as a waiter do it and do you feel it adds to the diner's experience and lastly as a guest do you feel comfortable when someone kneels down close to your table when they greet you?

Just wondering....
