HAN cafeteria prices are ridiculously high. However, the food quality and the variety of the items aren't that good. 
This is a place serving mainly students and teachers who by default have limited access to financial means. 
The prices of sandwiches are unbelievably high. It doesn't match at all the served audience. We don't seek a solution that involves reducing the filling nor reducing the sizes. 
We do demand a proper solution, a competitive prices to the supermarket at least.  Should the Cafeteria administration fail to provide these solutions, then they should move aside and give someone else the chance to run the cafeteria and maybe have a chance of success. 

If other places can provide better quality food with lower prices, then why can't you do the same?
