This booklet for servers provides instruction in the psychology of tipping as well as specific techniques that can be used to earn larger tips. All the suggested techniques have been scientifically tested and the evidence of their effectiveness is described along with the techniques.

Managers are free to download the file, print out the manual, make hard copies of it, and either post it on employee bulletin boards or distribute copies directly to their servers. Managers who distribute the manual to their servers should benefit from: Increased sales Greater Customer Satisfaction Lower labor costs due to reduced server turnover
