im way late to the game here, but i enjoy tipping. i always try to engage the waiter/waitress in some kind of light chit chat. i feel it makes their job and my dining experience more enjoyable. i rather them feel like a friend than an attendant. i dont recall this ever not working. so by the end of the evening im happy to leave a tip. its my way of saying thanks for alowing me to have more than just a good meal. plus i think they generally can use the extra 10 or 20 or 30... dollars more than i can.
