Philadelphia. I was about to check out and was mixing up my BCAA drink to take with me in the cab to the airport. The BCAA was lemonade flavor so it was a really fine white powder. I was dumping it into my shaker bottle and accidentally spilled a bunch all over the glass table in my room. Thought about cleaning it up but then thought ah what the heck, let the maid make her own assumptions. So I actually smeared it around a little and left her (cash) tip next to it.
