Was my dd being unreasonable?

My dd, in year 8, was in a lesson at school today when a boy asked to refill his water bottle, to which the teacher replied- "No, that is a lunch time activity". However, five minutes later the same teacher, while teaching, was booking his holiday and ordering furniture. My dd realized this and questioned him as to why it was fair that he is allowed to book holidays but they are not allowed to fill up their water, both of which are lunchtime activities. The teacher then shouted at her and told her she embarrassed him and asked to see her after class.
My dd promptly burst into tears as she is normally impeccably behaved and in her entire school career has only been in trouble once, the whole class went silent. After class the teacher told her what she had said was wrong and cheeky, but that he would let it go this time as it is completely abnormal behaviour for her. On the one hand I agree with her teacher that she was being cheeky in pointing this out, but then again I see her point. So was my dd being unreasonable? Is there any way she could have pointed this out without being "cheeky"?

MrsCaptainReynolds - agree with you completely.

OP, it looks like your DD has made an assumption about what her teacher was doing based on what she saw on his screen. Not unreasonable in itself, Y8 is still quite young to be able to think through all possibilities. However, just to look at it in another way, my y9 DD's maths teacher often uses exactly this sort of site when setting "real life" maths problems for the class. Imaginary budget of x pounds to book a holiday for y people, furnish your ideal house etc. The girls love it (and I think DD usually wins the prize for quickest overspend ) Perhaps it would be useful for your DD to put this one down to experience, and take the opportunity to talk through with her the positive things the teacher might have been doing. Then use parents evening to ask a few gentle but searching questions if you still have concerns.

I'm a teacher and I would not dream of researching holidays or furniture or anything else like this when I'm teaching. The teacher was in the wrong. Hopefully they
had a bit of a scare and will keep their focus on their class in future.
