I don't think tagging should be used to differentiate these questions. They could be easily missed. For instance, if we had 7 questions all titled:
What are some guidelines for appropriate social drinking at work?
and all 7 of those questions had different tags, it might not be clear to everyone that the scope of the question is somehow tied to the tag.
Tags should be used to categorize questions, but they should not be required for a reader to understand what the question is about. Instead, the question should contain enough detail to stand on it's own without the tags.
On StackOverflow, when I answer a JavaScript question, I can tell the question is about JavaScript simply by reading the question. The questions stand on their own without tags; I don't need the tag in order to tell me it's a JavaScript question. However, when searching for JavaScript questions, the tags are very helpful.
Thus, we should target questions like:
I work in the United States, what are some guidelines for appropriate social drinking at work?
I live in Afghanistan, what are some guidelines for appropriate social drinking at work?
Additionally, these details don't necessarily need to go in the question title. They should also be included in the question body.
