Safety trumps etiquette. I would call the city ordinance or fire marshal to complain.
I don't actually think this is a situation where "safety trumps etiquette" applies. There was no immediate emergency; this was a concern about something that may happen in the future. As such, there are still polite and impolite ways to go about expressing one's concern. The initial complaint was polite; I think the "what if I called the fire marshal right now" comment was snide and unnecessary.
So one waits til there is a fire? This is in anticipation of safety. I don't believe the comment was snide at all. It is the wise thing to do since the manager didn't seem concerned about a fire danger and breaking the law. They most likely block the doors for their safety, but in doing so, they are putting their customers at risk if there is a fire.
Oh, sweet mother of Ehell,
no, one does not wait until there's a fire. You are completely misinterpreting me. My point is that when there is a
concern rather than an immediate
emergency--and if you check my earlier posts in the thread, you'll see that I'm really concerned about the issue--when there is a concern rather than an emergency, one can phrase things politely. One still says them--but the phrasing is different.
If there's an actual fire, you don't go "Sir, might I bring it to your attention that there is a fire?" You just say "Fire" or pull an alarm. But when there is not actually a fire, there is room for social niceties in the phrasing. It doesn't actually take any longer to phrase it more nicely, and the odds of a fire breaking out
while you're in the middle of asking about it are infinitesimal. I just think "safety trumps etiquette" is so overused it's become ridiculous.
If you disagree with me that the OP was snide, that's fine. But please do not characterize me as wanting the issue swept under the rug, because that couldn't be farther from the truth.
