An extremely strange practice to Americans, but very common in China, includes wrapping absolutely everything in excessive amounts of plastic. Stores make a point to wrap and double-wrap candy, books, refillable water jugs, and fruit in at least one layer of plastic.
It should come as no surprise to me that restaurants also wrap their sanitized dishes in plastic; Chinese people seem to equate plastic with the word “clean”. One of the first phrases I learned how to say was “wo bu yao bao,” which means, “I don’t want a bag.”
If it’s in plastic, it must be better, right?
