Recession tipping! What a concept. I spent one summer in college waitressing at a not-so-fun restaurant with a not-so-fun boss, and tips were all we got. The less a customer tipped us, the less we got paid. One night, an incredibly chatty and very generous woman tipped me 40% ("to give you a head start on student loans," she told me). Three years later, I can still remember her face. Needless to say, I always tip at least 20% when I go out for drinks or food, and insist (often to the point of annoyance) that others tip a fair amount. Even when I feel strapped for cash, it's a sobering thought to remember what it's like to be completely dependent on the tips of others.
