Being dedicated to your job is admirable and the journalists at The Grocer often scour the world for the greatest stories - often at great personal risk to pride and person.

But one employee has so much pride in their work that I felt they deserved a shout out. For one Coca-Cola lackey, finding out the number of bubbles in a can of Coke became an obsession after a member of the public posted the enquiry on Coke's website. The employee knew each can was carbonated to 3.75 volumes, meaning there were 1237.5 cubic millilitres of carbon dioxide. Using the average diameter of a bubble, he calculated that every can contained 18.9 million bubbles. Now that's geeky dedication.
