In fact, other restaurants that offer free napkins may not be "free", but they just add a napkin to the dishes invisibly. In fact, everyone can accept this way of collecting money more. Adding a dollar to the dish is painless, but if the paper towels are charged separately, everyone will be wary, and even start to bring their own napkins instead of buying them from the hotel, or buy a box to save and take them home after dinner.
Only those who spend money to buy it will know how to cherish it. If the hotel provides free paper drawing, because everyone thinks it's free, it won't be saved, and it's often just a pile to use, and waste will appear. This is not only the cost burden of catering practitioners, but also increases the output of garbage invisibly for environmental protection, and also sets a bad example for customers with children.
In the past, Xi 'an's restaurant did not provide free napkins, but in order to reduce costs, the paper quality and hygiene problems of napkins were not up to standard, and the rough napkins not only made consumers dissatisfied, but also were reported. Under such circumstances, restaurant owners naturally stop doing such thankless things and charge for providing better quality napkins or don't provide napkins for people to bring. Anyway, there is no provision for the catering industry to voluntarily provide paper towels.
In fact, providing paper towels in restaurants or charging for them is very beneficial to environmental protection and avoiding waste.
