I Hate Waiting

So my boss told me only yesterday that I had to present to management today... my slot was 9.45am but they're running late so it's been pushed back... till god knows when. It's now 10.06am. I have to prepare for another meeting this afternoon but I'm stuck here, waiting. If it were at the office I could at least work while waiting but noooooo, it's at a location 40 min away. Guess I'll be working through lunch, lol.
