In the summer of my freshman year of college I worked both in the kitchen then as a server. In the kitchen we were paid a higher hourly wage, but of course got tips as a server. This was 1980, but I figured my average hourly wage as a server to be $9-10 per hour vs $3.50 per hour in the kitchen. Guess where I was happier?
The entire tip culture is screwed. It is indeed corporate America expecting the population as a whole to subsidize its workers via tips.
