First, the problems about seat are not enough, dirty and damaged. In the canteen there are 20 tables that each table has 8 seats so all seats about 160. But the students can’t use every seats. Some of them are dirty because of food scraps, water, stain, bird excrement etc. And some of seats are ruin such as backrest has broken, seat legs are not equal. From this reasons, the students doesn’t have seat for eating and drinking.
