The other day I was at Starbucks and the person in front of me in the drive-thru line bought my coffee and breakfast sandwich.  When I pulled up to the window, the cashier/barista told me the person in front of me had paid for my coffee and food. 

Did I want to take the free meal or pay it forward for the person behind me?  I'm a huge believer in karma.  I paid it forward.  The car behind me ended up being 3 people (all ordering breakfast).  It cost me $20!!!
