Interesting blog post by the San Francisco Chronicle reviewer Michael Bauer about an email he received from a Berkeley restaurant chef/owner:
"Customers have begun threatening to 'Yelp' the restaurant if their ... comps were demanded with the threat that a harsh review would follow on the Yelp website if we didn't comply. ... People do follow through on their threats ..."
That email doesn't really put things in an adequate context. Did these customers make the threats as simple blackmail, or did the threats arise during a discussion regarding a complaint regarding bad food or service?
