sam2 – sorry, I just don’t think that’s true. I don’t know what my friends do or don’t eat.
Of course they’re believed that they’re not trying to give me something I wouldn’t eat – they simply don’t know.
I don’t think there is “kosher by your standards”. There are so many individual questions, as well as differences of opinion (or rumour!) about different hechsheirim, that I just don’t think his giving it to you tells you anything about whether you would want to eat it.
