" I read "Keep the Change," a follow up to Dublanca's first book "Waiter Rant" because I was very entertained the first time around. This work takes on a more investigative journalistic approach, which I found enjoyable and surprisingly informative. Discussing the economy of gratuity, Dublanca's quest to become a Tipping Guru took him to some of the seedier sides of our culture, exposing the both the necessity and etiquette of greasing the palms for those who provide services many often take for granted. As a laymen who has never worked in the service industry, I found how much tipped employees not only rely on their gratuities, and was immediately wracked with some guilt for slights dues to my ignorance. Dublanca's exploration of the history of tipping and the importance it plays in society really opened my eyes to this often overlooked aspect of our culture and I feel more informed and better prepared next time I am in line at Starbucks or handing my keys over to the valet!
