One thing that annoyed me was that we were obviously unable to solve the puzzle and the guy kept giving us hints over the comms.
I told him to stop several times (since it wouldn't matter - if we can't solve we'd return another day). Though he must have had instructions to push all customers into a "successful outcome" no matter how poor they do. For that I was furious - though will certainly go and check other companies next time and make it clear that if they do give hints (no matter how bad we do) they won't get paid.
lastly there was news just last week that one of these rooms burned down in Poland. Sounds like a backstory to one of the "The Saw" films:
