Today was dd's sports day. The advertised time was 1.30-3, I told dd I couldn't come to the whole things as I had to work but I would be there for the final few mins (20mins ish before the end) she was disappointed but happy that I would at least see some of it. So I finished work a little early (time I will need to make up) and turned up about 2.40 to see the final few mins to find that it had already finished, in fact it had finished at around 2.30!! I was really annoyed that after making a special effort I missed the whole thing. I appreciate that as a working parent I must accept I will miss things but I tried. DD is not normally the sort of child to worry overly, but she actually cried at pick up time today which is most unlike her. She said it was because she had lost but I think it had more to do with me not seeing any of it 
My question is, is it worth mentioning to the school that it is quite annoying that it finished way before the advertised end?
I know is not a huge deal but I just feel like they are always doing this sort of thing, small annoying things rather than major issues but all that happens is people moan at the gate/on fb and never actually tell the school.
I'm not sure if there's an issue worth mentioning of if i'm just tired and grumpy
