It was obvious that Darren must be an economist given the self-confidence of his response. His current silence also speaks volumes.

My silence spoke to the fact that I have a job.
The idea of a "multiplier" was in the news a lot during debates about a federal stimulus plan. The idea is if the government spends $1 trillion on goods and services, GDP will rise by more than $1 trillion. When the government pays $100 to a contractor, the contractor saves, say, $10 and spends $90. The person who receives the $90 perhaps spends $80, etc. So the $100 initial spending by the government turns into $100+$90+$80.... total additional spending.
The key thing is that the government is spending money that wouldn't have otherwise been spent. (The reason this type of fiscal stimulus is controversial among economists is because some make the argument that the money isn't, in fact, new spending. That's a more complicated issue that is better left to LTHEconforum.com or private messages.)
The infographic is attempting to draw the analogy that when you spend $100 at a restaurant, the restaurant ower pays some of this in wages to employees, pays food vendors, spends some herself, etc. The employees and vendors then spend their earnings. And so on. So your $100 at a restaurant generates more than $100 in spending.
As I said in my initial post, the problem with this analogy is that if I didn't spend the $100 at restaurant X, I'd spend it at restaurant Y, or at Whole Foods, or at the Green City Market, etc. Unlike the government spending story where there is new money injected into the system, when I decide to spend money at a restaurant, that is money (and the associated multiplier) that was already in the system. The $28 that I spent at Xoco was going to generate, say, $100 in total spending whether I ate at Xoco or not.
