Just wondering, do you cook mince, rissoles, sausages, or anything else made from minced meat, all the way through?

I went to breakfast a few weeks ago at a friends place and they cooked sausages still pink... when I asked they said they like their red meat pink...

I went to a BBQ where someone cooked their rissoles pink... I asked and same answer...

I was seriously grossed out so didn't eat either... I always thought you were supposed to cook minced food all the way through...? Or am I just being pedantic?
