Three years after high school graduation and after quitting college, childhood friends Marcelo and Barry find themselves waiting on tables at the popular Vineyard Restaurant in St. Petersburg, FL. A year earlier they had made a pact to work, save and open their own place, but Barry's wasteful spending had derailed those plans. One evening Barry is captivated by Emily, a new waitress on vacation from her studies at Miami State, but her eyes are set on Marcelo. Soon their lives soon intertwine in the summer of 1978 - a season that would bear rewards for heroism, the bliss of romantic love, and the despair of insanity. "Gratuity Not Included" will strike a cord with every reader who has questioned the best-laid plans, has been inspired by love, or has been bound by loyalty.

Asymptotic analysis is an old subject that has found applications in vari- ous fields of pure and applied mathematics, physics and engineering. For instance, asymptotic techniques are used to approximate very complicated integral expressions that result from transform analysis. Similarly, the so- lutions of differential equations can often be computed with great accuracy by taking the sum of a few terms of the divergent series obtained by the asymptotic calculus. In view of the importance of these methods, many excellent books on this subject are available [19], [21], [27], [67], [90], [91], [102], [113]. An important feature of the theory of asymptotic expansions is that experience and intuition play an important part in it because particular problems are rather individual in nature. Our aim is to present a sys- tematic and simplified approach to this theory by the use of distributions (generalized functions). The theory of distributions is another important area of applied mathematics, that has also found many applications in mathematics, physics and engineering. It is only recently, however, that the close ties between asymptotic analysis and the theory of distributions have been studied in detail [15], [43], [44], [84], [92], [112]. As it turns out, generalized functions provide a very appropriate framework for asymptotic analysis, where many analytical operations can be performed, and also pro- vide a systematic procedure to assign values to the divergent integrals that often appear in the literature.
