I'm not a native English speaker either, as you know, but this sentence without articles sounds very very odd to me. As any sentence without articles would. But I guess it is is British slang because it doesn't sound that odd, it just doesn't sound American.

But this whole thing totally reminded me of how oddly article use in Germany differs between Southern and Northern parts of the country. I moved from Hamburg to Stuttgart a year and a half ago and it was so odd to me that everyone would refer to other people as 'der Hans' or 'die Lisa' or whatever. Their use of articles is really very extensive. :D

As for addressing teachers, I worked in three different preschools in the last three years and in all of them I got addressed differently. In the first they said 'Frau Nachname' (according to the head teacher that was because they wanted the parents not to address the teachers by first name, which they apparently did when the children were calling them by their first names), in the second one they said just my first name and now it's the Polish equivalent of Frau and my first name. Or just Frau when they just want to ask something. Basically 'excuse me Miss', which was very odd for me at first because in Germany we would obviously only use 'entschuldigen Sie' when we want someone's attention, but I think in English it's more common.

Heee, language discussions are fun. :D
