Email is the sharpest sword in the arsenal, and the most frequently used. If you want to be "in" on what's happening at Excaliburger this is it. All relevant information that makes its way to any social media was first and often times only shared via email.
...also free stuff, exclusive parties, discounts, blah blah blah. Booooring. You should probably just keep being a bottom feeder and grab whatever leftovers float your way on Facebook.
