99.9% of times when I go to fast food places I'm alone and don't feel out of place doing it. I've never been to a sit down place with a wait staff, etc alone though. If I'm going to spend the money at a place like that and leave a tip, it's usually because I'm going to dinner with a friend or something. I also rarely if ever see people eating alone when I go to those restaurants.
And if I'm eating alone I generally like to get something quick and be out the door fast. Eating at a nice restaurant, is supposed to be enjoyable, but I'd get bored fast without someone to talk to and want to be on my way. No real point in me going alone.
Underneath the cold November sky, I wait for you... As the pages of my life roll by, I wait for you... I'm so desperate just to see your face, meet me in this broken place...
Be a little brave for a little bit of time.
