From comments at other sites from people familiar with the school and the family and this incident; it becomes clear that this is not about some poor girl being picked on. It appears it is the hotel that made the rule that no food be allowed in the room as a condition of the school being able to book rooms there. Several people have commented that the family and the girl are known for being bullies.
I’d question what they call bulllying. Maybe it’s true. But it is still an asinine reaction by the powers that be.
The article was unclear about who made the rule, just that it was a rule for “trips”. Thanks for the clarification.
So for others following, it is the hotel that is Hitler.
