(I wish I were kidding about this, but I am not.)
Ok... so we had a bunch of the new MBPs at work and kept having keyboard issues (like 50% of the team complained about the keyboards and had keys that stuck within the first 3 months). I brought one machine in to the Apple Store and was scolded for eating while using the computer. "Hey Guys, I'm sorry that humans weren't in your target audience focus groups -- the new butterfly keys are amazing!" Wasn't even my machine... just doing a favor for a friend. Ugh.
