If I ask anyone for a glass of water, they're going to get me the same thing because they know what I mean. No one is going to get me a glass of orange juice or tea or 7up, even though that's technically also water.
so then do you agree that they wouldn't bring you lemon water or cucumber water? clearly you didn't ask for those. but OP explicitly calls those out as 'no goofs'. so where's the line?
The whole point of this conversation is that OP is excluding drinks on some arbitrary line that no one else understands. If lemon water isn’t allowed then what is?
OP is excluding drinks that aren't regular water, this isn't complicated.
If you went to a restaurant and asked for water, what would they give you? Probably something from the tap, or a bottle, or a purified pitcher. Maybe mineral water, but that's as much additive as you're going to get. It wouldn't even be sparkling, and they're certainly not going to give you milk and smugly tell you "well TECHKNIQUELLY its water!" you damn dork. You know what OP means, you're being ridiculous.
Cucumber water is not what you'd expect when asking for water, yet OP excludes it as being invalid for being equivalent to water. So where is the line?
Tea is absolutely my non-troll answer, but how different is that really from cucumber water in this context?
