Why does the waiter bring a plate of white radish when eating buffet?

Nowadays, there are more and more cafeterias. There may be five or six cafeterias on the first floor of a shopping mall. At first glance, the business of each store is not bad. Ten years ago, we wouldn't have seen such a scene. In the past, the form of canteen was relatively simple, and there were few kinds of dishes. Unlike now, there are many ways to eat, such as buffet hot pot and barbecue.

Yang zai actually likes to eat buffet, because he can eat whatever he wants after he enters the store at a certain price. There are many kinds of food, and it is quite enjoyable to eat. However, many people will have this purpose, but do you think he can really eat back? After all, businessmen will not do business at a loss. In fact, as long as they can eat happily and satisfy themselves.

I like Andy, and I often go to eat barbecue buffet. However, when eating barbecue buffet, I wonder if you have found such a problem, that is, the waiter will give you a plate of radish slices as soon as he comes up. Obviously, we didn't order this thing or ask her for it. Why did we send you a plate of radish slices? When it comes to this and white radish slices, many people don't understand its meaning, so they eat it and make a big joke.

In fact, the carrot slices served by the waiter are not for us to eat, but have their own special usage, that is, when we barbecue, it is not easy to clean all the sauces on the baking tray, so it is easy to get burnt when we barbecue. In the face of such a baking tray, the white radish handed over by the waiter played a great role, that is to say, we should wipe the baking tray with this radish slice, and wipe all the sauces on it with the radish slice after each baking round.

Of course, many shops are aware of this now, so they will spread a layer of oil paper on the baking tray. If it is burnt, just change the paper directly, which saves a lot of trouble and saves a lot of things for the store staff when cleaning the baking tray.
