GrubHub (which is a fantastic app btw.. jussayin) complied a bunch of their data to decide which cities in the U.S are the best and worst at tipping.  It turns out that Western & Upstate New York got called out pretty bad.  We suck as tippers.  Our average tip is 13.4%.  It's bad enough to be the 4th worst in the country behind Syracuse, Ithaca, and Champaigne (Illinois).

As for the best tippers.  Colorado wins big.  They own the top 3 spots.  Boulder is #1 with an average tip of 16.2% followed by Denver and Ft. Collins.
