Thanks, Jen - a fascinating read! I had to go and look up that list of 301 ways you know you've been in China too long, and am amazed at how little has changed in the 12 years since I left - this debate being one of them. I've had Chinese friends who would deliberately throw their rubbish out of train windows "because some people who live in these areas rely on picking up that stuff and selling it to make a living". Not something I could ever do, but not clearing a table in a restaurant would be much more borderline, I think (China didn't have Starbucks when I was there, so the dilemma never arose for me).
