There are many tricks behind the "packaging fees" for takeaways, and consumers can protect their rights in a variety of ways. Some takeaway merchants increase packaging fees to transfer costs.
Some restaurants charge separate packaging fees for each dish, but in fact the goods are combined and packaged. Most catering takeaways charge a packaging fee of 1 yuan for a single dish, and some charge 2 yuan/portion, such as "Rongyi·The Beauty of Sichuan Flavor". The more dishes you order, the takeaway fee will increase accordingly.
