The funny folks at the “Short Order” blog at the Miami New Times have rounded up a list of the most parsimonious celebrities when it comes to tipping. Madonna and Sean Penn’s marriage didn’t survive, but apparently their love of thrift did. Cutie foodie Rachael Ray and pudding pitchman Bill Cosby, among other well-off, well-known folks aren’t known for their generosity either. This revelation, coupled with professional wealthy person Warren Buffet’s recent call for higher taxes for the highest earners, has us wondering if celebs and the really rich should be expected to leave extra-large tips when dining out. Tell us how you feel in today’s poll below.
