Here’s a suggestion.
If someone representing a business you’re dealing with, from the person taking your order at the drive through to a service person fixing some sort of problem for you, and they do something that impresses you, go public with the praise for that person and business.
From Urbanspoon to Yelp, from Facebook to Twitter share the story. Everyone wins!
I wonder if we did this more often if we could overcome so much of the rampant negativity that seems to be everywhere?
