MaccyD's fries are vegetarian society approved in the UK.
It is worrying that I find it safer to eat in maccys than I do eating in a restaurant. It's the ******* parmesan. Every single bloody restaurant smothers their vegetarian dishes with ******* parmesan. IT'S NOT VEGETARIAN! By law in the EU, parmesan is NOT vegetarian. And if you're using an Italian hard cheese that does not contain animal rennet and labelling it as parmesan (because real parmesan will contain animal rennet), then you're breaking EU law. And I'm pretty certain it's illegal to label food as being vegetarian when it's not. Although most restaurants get around that by having meat-free options on the menu but not labelling it as vegetarian.
And yes, I could ask for them to not put the parmesan in, but I just don't trust whatever else is in the meal.
At least with maccys I know what I'm getting, I know the ingredients and I know the cooking process:

As for it being maccy's, I don't see it as any different as buying my food from the supermarket which also sells meat.
(Although I don't actually choose to eat there. It's when family wants one when we have no food in the house but want to eat before we go to the supermarket to do the weekly food shop. However, if I was to be out and about and in need of food and my choice was between a bunch of restaurants that shove calf rennet into all their meat-free dishes or eating at maccy's, I'll pick maccy's. )
(I get the vegetable deluxe burger. If anybody wants to see what is in one:
