Today, when I dropped in at McDonald's in front of Osaka-Uehonmachi station to eat a Texas burger*1, I could hardly find my seat to sit down.
It was mainly because some seats were occupied by many students who were studying in McDonald's for a long time.
In the end, no seat became available to result in that two customers came after me were forced to eat without sitting. And a employee who saw the situation apologized to them.
In the case, employees should scold students who remain only to study in order to ensure vacant seats for the other customers.
Even if some students are going to take entrance exams which are near at hand, it is not acceptable to occupy seats without eating in McDonald's.
*1:I don't know whether it also exists in Texas state. At least, it is sold in Japan.
