Went on a training course after work (5.00 - 6.30). Was interesting but the speaker was very dry and monotonous (think the teacher from Ferris Bueller) with lots of ummmms and ahhhhhs. He also went off on a lot of tangents and stopped for the group to have a coffee break half way through- people had had coffees etc at the start and brought them over to their tables, and no one knew each other so there wasn't any chatting during the break, just a few people shuffling over to the coffee/tea table and most people checking their phones.
Was I unreasonable to have written on the feedback form: "X was useful and interesting, however I feel it could have been condensed to 1 hour or less- the pace was quite slow and some discussion unfocused, and a coffee break isn't necessary during a 1 hour 30 minute session."
I feel a bit bad about it, but I have 5 more sessions of this fortnightly for the next 10 weeks and am hoping they will either consider making it an hour in future or making the speaker a bit "pacier" (somehow). I would even rather stay for 2 hours at a time and get two sessions done in one which would have meant less sessions.
So was my feedback rude or constructive?
