"All in?" asked as a question, not a statement - ruling?

YTF - Do you seriously rule this a call?
I see this happen at least once or twice almost every time I play live NL.
Surely you must run into this multiple times practically every day.
People just too lazy to say "Is he?" before they say "all-in?" and have seemingly no clue that their question could be cause for some confusion.

This stuff annoys the crap out of me but it's usually done innocently by people who just don't know any better and aren't thinking.
I have yet to see it done where I thought it was an angle-shoot.
