How many minutes to earn the price of a Big Mac?

a UBS report published this week offers a handy guide
to how long it takes a worker on the average net wage
to earn the price of a Big Mac in 73 cities.

Fast-food junkies are best off in Chicago, Toronto and Tokyo,
where it takes a mere 12 minutes at work to afford a Big Mac.
By contrast, employees must toil for over two hours to earn enough
for a burger fix in Mexico City, Jakarta and Nairobi.
