Tonight after a very long day at work...nay, a series of very long days...I stopped by Cracker Barrel to get a bite to eat.
Much like the 
Applebees experience of last year, I sat there apparently invisible to the wait staff.  The person who'd originally sat me down was nice enough, and I made eye contact and smiled with all the waiters and waitresses that passed by.  The hostess then sat a couple directly behind me.  A waitress immediately stopped by, took their drink orders, then returned with liquid refreshment.
At that point I got up and left.  The hostess thanked me for visiting, to which I replied "Maybe next time."
Maybe I should have said something, or asked for a manager.  I still feel like a dick if I do, and believe me I mulled this over and over before finally leaving.  But if there's one thing that I can't stand it's to be ignored, for some reason that jerks my chain real bad.
