I’ve been told “I owe you a beer” numerous times, by sales guys, after I solved their computer dilmena. I guess if the fiat monetay systems collapse, I know we can at least use booze as a system of currency. I’m not a drinking man, but there’s something about hearing that phrase that makes me feel better than just being told “good job,” or “thanks;” it combines heartfelt appreciation with a manly respect. I submit for your consideration that if your desire is to express gratitude to another man, no better phrase exists.
