Sir – Last Friday, I was visiting Oxford when I saw groups of students throwing food and drink over each other.

My sister informed me that students do this to celebrate the end of their exams.

I am truly appalled that in the current climate of global poverty and starvation, and the rise of food banks that privileged, arrogant, thoughtless and over-indulged students can do this.

They should look around and beyond themselves and look at the inequality of the world we live in and, perhaps, donate food to foodbanks instead of wasting it.
