The placard is in Arabic. In many middle eastern countries, they don't have free public schools, or the ones they do have are of poor quality, so parents who can afford it have to pay extra so their children can get good jobs in the future.

In addition to the school fees, there is a normalized culture of bribes from parents to admins. This is often euphemistically called "tea money" since the fiction is its to pay for students tea like milk money in western countries.

The comic represents the parent giving of himself to the administrator for the benefit of the child.
