This is the main school entrance. The bucket in the corner is for garbage and especially for cigarette butts. In Bulgaria smoking in school is forbidden, but teachers and students can smoke on the street. The students-smokers are usually impatient to go outside during the break and light a cigarette. There is no need to look at the clock to find out if the end of the class is approaching as they stand up sharp at the moment when the school bell announces the beginning of the break.
