When one is baned from a college for drinking, normally there is some evidence that is provided, one does not simply get turned away from a college's gate, and no college would be allowed to trade as an educational institution, or as any other institution for that matter, if its charter stated that it has the right to turn away fee paying students without having to provide a valid reason. If that was to happen, the person turned away would be entitled to a lot more than a refund to their already paid tuition fee. I'll give you $5 to shut up and stop whining.
