The beginning is simple: the people who work at the bookstore the night of your event also sell books all day long, which means they are very, very powerful people. If you are rude to them, guess what?! Your book will not be the first one they try to handsell to customers. If you are nice to them, they will always think of you fondly, and your book is more likely to be one they recommend. This is not bribery, mind you, it is basic human decency.
