That's a good point, and it also highlights a corollary. Restaurant servers and their advocates often defend their efforts to increase the percentages (from the standard 10% for buffets to 15%, and from the standard 15% for table service to 18% or 20% or higher) by asking, "When we restaurant servers get a pay increase?" However, the reality is that while the rest of us are at our employers' mercy when it comes to getting a pay increase, restaurant servers automatically get a pay increase whenever their employer increases prices. Their income is directly tied to the rate of inflation.
