I feel like I'm seeing more and more etiquette questions that are probably just vents. OPs may ask a question, but if people disagree with their actions, it becomes apparent that they really didn't want dissenting opinions. They wanted validation. For instance, someone might say, "Today I refused to tip my waitress because it took her 1.5 minutes to bring my coffee and it usually takes 1 minute. Was I rude?" Ten people say well, an extra 30 seconds doesn't seem like a lot, and maybe there was something going on in the kitchen, and maybe the coffee was still brewing, and really, anything under five minutes seems like good service. The 11th response is, "I don't blame you. 1.5 minutes is .5 minutes too much to wait for coffee!" and the OP will say, "Finally, someone who understands!" Or, the OP will tell the naysayers that they'll just have to agree to disagree on this topic.
I don't think we're in any danger of becoming a vent board, thanks to our moderators and a healthy degree of self moderation. And I think it's good and healthy to occasionally say, "I'm having a bad day. The service at the coffee shop was slow and I just started my day off grumpy. Can I have a hug?" But I want to suggest that we be honest with ourselves before posting a question. Do we really want answers, or do we want to be told that we're right? Because I think the beauty of this board is it makes us take a good look at ourselves, and if we're not open to considering other answers, what's the point of posting the question?
(And if everyone disagrees with me, I promise I won't come back and say we'll just have to agree to disagree.
