Sydney Spy Classic
If walls could talk, you might not be so miserable since you're facing one. The typical posture when eating a hamburger is very slumped over, 2 hands around the sandwich. You don't bring the burger up to your face, you go down to it and its all-powerful hold.
Typical of The SydneySpy© The Misery Seat©®TM, it is situated next to heavy foot traffic. So if you decide to look up between sweaty bites, you may get some darting eye action from people walking by. They could have used that space for a tofu bar or Pilates mat, shocking!
Any misery seat is a happy seat with you commenters though <3
