? It is also effective for fast food restaurants to pay by weighing and eliminating waste. Because the conditions are getting better and better now, many people don't know how to cherish food, but because every grain is hard to come by, we all need to accompany and cherish it. Because every grain of grain is hard-won, we should respect the fruits of farmers' uncles' labor, because it is also the grain they grow with sweat, so I am now in today's society and I should understand how hard life is now. In the past, our parents, grandparents and others did not have such good conditions as we do now, so we should cherish them. ?

I believe that when we were young, we all recited the poem "Who knows that every grain on the plate is hard", so we should also cherish food more. It is also difficult to understand food. Because there are still many people who have a hard life, food may not be so adequate, and conditions are not so good, so in fact, we have such good conditions and life now, so we should cherish it. Because in fact, while we cherish food, we also respect the fruits of farmers' uncles' labor, so we also learn to cherish it more. ?

Cherish food, but also carry out CD-ROM action, and resolutely stop wasting behavior, because a porridge and a meal are hard to come by, and a wisp of persistent thinking is difficult. It is not easy.

So to sum up, it is an effective way to prevent people from wasting food by weighing and paying the bill in fast food restaurants.
