today i grabbed the wrong coffee at the coffee shop and took a big sip while the real owner stood right there watching, his name written in big black marker on the side of the cup. i said sorry, put it back on the counter, then picked up that same wrong cup again the second my name got called because my brain had already left the building. what is the most embarrassing wrong order mixup you have ever had to fix in front of a room full of strangers?
