Teachers described the experience of taking unfinished meals home from a restaurant in a doggy bag, in the hope of instilling in their students the understanding that it is better to enjoy leftovers later than to overeat now. (And, my Silicon Valley perspective told me, the restaurant could increase its revenue by selling ads on the sides of the doggy bags.)
其中一站是宾夕法尼亚州的兰开斯特（Lancaster），我们在一所小学与热心健康和公益的公民团体见了面。教师讲述了在饭店将未吃完的饭菜打包带回、以期向学生灌输随后享用剩菜比当时吃得过多更好的观念。（而我的硅谷视角告诉我，饭店还可以通过出售打包袋广告增加收入。）
