Oh come, I know we would all defend a good employer (and they are that) but your oft repeated protests on McDonald's being "real food" are transparent shilling.
It's crap, sugary, syrupy sweet crap at that, and highly calorific junk food. Yes I know it's real beef, real coffee beans, real potatoes... (but it's a sad company who needs to assure people that its beef comes from cows and its chips come from potatoes). Tellingly It's also real sugar, from sugar cane, and real fat, from animals, and lots of it, in both cases.
A *medium* big mac meal is over half the calorie intake of what a human needs in a day, and people have that for lunch, not their main meal. Go large and you're at the threshold of that being all you're allowed, (unless you like wearing size 22 dresses as a matter of course).
Yes, you eat it occasionally and yes, it won't kill you occasionally, but the constant queue of people at every "I can't even be arsed to get out of my McCar" McDrive is testament to the fact that for many it's far from occasional. It's a long term habit.
Its terrible, sugary, highly calorific crap which is helping lazy Brits become ever more obese and lazy, and shame on you for defending it.
