In the cases of McDonald's and Nanja shopping mall, which among any Chinese of any level are known to have quality toilets, are pure laziness and being a douche. Nothing more.
I asked my spouse about it, if it's normal. It's not.
On the subway, yes it's a difficult situation. They give clothes with no bottom to the kids, so they can do it anywhere any time. The parents often are uneducated and mostly just too lazy to bring their kid to a restroom. Or don't want to spend money and time of buying and changing diapers. Plenty of exceptions exist too where the parent do being kids to a restroom.
You just don't expect the "fresh" counter to be watered in that way.
Advice: wear non-slip shoes and don't pick up any fallen produce off the floor.

Posted byOf what I have seen the problem lies in the amount of sugar used in cooking rather than the amount of junkfood consumed (which tends to be very high in salt). People don't like too much sugar as in pure sugar or sugar in drinks and snacks, yet if you see how much they use in cooking (they put in bread, sticky rice milk, etc. too), my goodness how much that is.
Many dishes people like to eat are very high in sugar content. Orange Beef has a ton of sugar as far as I know. But it's soo tasty!
