When I was a child, the set of rules were pretty common: * Don't tip at counters * Don't tip the owner of an establishment * Tip on the quality of the service, not the quality of the food * Very low tips should be utilized only in case of very bad service. (A penny tip sends a much bigger message than no tip) * Round up to the nearest dollar for taxi drivers or Ubers, since they are almost all self-employed, and you don't tip bus drivers do you? Also, I only tip in cash, and only by putting that cash directly in the hand of one of my servers. Otherwise the manager, who is not supposed to be tipped will likely take a cut.
