So it's clear we dearly love the fast food giant - but if your partner enjoyed a Big Mac without you, would you go as far as putting it on a par with cheating?
More than one in 10 adults would apparently...
According to a poll of 1,000 fast food fans, one in 20 are desperate for a taste of Maccies after months of going without and would break up with their other half if they went for a sneaky drive-thru alone.
The remarkable devotion among its customers is also highlighted by claims from one in five that their first taste of a Big Mac after lockdown was better than a pay rise (17 percent).
Meanwhile, 16 percent of loyal Maccies fans even rated the feeling as being on a par with the birth of their first child (who are these people?!) and 13 percent considered it to be better than their wedding day.
Imagine comparing your kid to a £5 meal.
The poll also revealed 16 percent of those who have enjoyed a McDonald's since restrictions were lifted, considered it to be better than getting a promotion at work.
And almost a fifth felt happier than if their favourite football team were to win the league.
A morning Sausage & Egg McMuffin on the way to work was the occasion most missed during lockdown (22 percent) followed by family trips to the drive-thru (21 percent) and weekend stop-offs while out shopping (21 percent).
But there was stress for some desperate customers polled, via OnePoll, thanks to the idea that we might one day have to go without again - with 46 percent claiming they would rather give up booze than their favourite burger.
Almost one in 10 would prefer to go without their mobile phone and 29 percent would rather skip watching sport for a year if it meant they could get their hands on a Big Mac. Alright, they're good but are they that good?
Well, no one will have to give up anything soon because McDonald's restaurants will reopen dine-in areas from Wednesday 22 July across the UK. Drive-thrus are already open.
About 700 of the chain's branches will open for people to eat in as of tomorrow - except for in Wales - following a successful trial.
The move also means that some of the restaurants can take part in the Chancellor's Eat Out to Help Out scheme, offering 50 percent off dine-in bills, up to £10 on Mondays, Tuesdays and Wednesdays in August.
These McDonald's lovers might as well set up camp.
