Too bad that I'm still good at math when I am drunk. I was out at a bar one night, and I "came to" walking down the railroad tracks on the way back home (way out of the way, and not exactly safe). I didn't even remember cashing out my bar tab, but lo and behold, when I checked my credit card transactions a couple days later, I tipped right around 25% ($85 total on a $67 tab) -- this is the same way I would tip sober. If you want a moral in this story, don't drink two 1-liter mugs of micro-brewery beer within a couple hours and then continue drinking Guinness and shots ($30+ worth!) after relocating to a popular Irish bar.
