blink, you implied that they inject the patties with partially hydrogenated oils, which is not true. most meat products contain a small amount of trans fats naturally, which have never been shown to be harmful. this is one reason why food labeling rules in the US allow amounts under 0.5 grams per serving to be reported as 0 grams. Canada, among other places, does not allow this.
and yes all my claims assume you're in the US, bros across the pond will need to adjust their expectations accordingly.
