Personally, I think this should have been challenged at the time - politely by saying something like if you don’t mind, I’d prefer to open the paddle. If he subsequently refused or was rude then by all means complain. Unfortunately this smacks of people who have a poor experience at a restaurant, don’t say anything at the time but then go and give a poor review on Tripadvisor. (And no, I’m not a restrauteur or anything similar!). I just think that things like this are better dealt with at the time, get it sorted and move on. For me, life’s too short to complain about something that could have been sorted in an instant.
