Please help me think of some canteen slogans

The era of educated youth has passed, please don’t “jump in line” anymore.

The food passes through the intestines, and courtesy remains in the heart.

The school cafeteria is really big, and it’s up to everyone to keep it clean and tidy. Please queue up when you come to buy food. It’s really wrong to rush to be the first.

Even if you are hungry, you must remain graceful.

The food in the cafeteria is delicious, so be courteous when buying food.

Patience is a virtue and means a lot of waiting.
