The best bartenders have been learning for years. You don't learn (among other things) how to mix dozens of drinks through osmosis.
Plus, they have to deal with numerous drunk-ass idiots every night. The reason I'll (hopefully) never bartend again.
Good bartenders earn their money a whole lot more than office jockeys who spend their workdays typing away on Free Republic.
Give me a break. Except for fine restaurants, most bartenders know little else than how to pop a top off and mix a hi-alcohol shot for drunk college kids.
And btw, I was a bartender many years ago. I earned more in 4 months of partying and carousing with the customers than my annual income for my first 5 years with a “real job”.
