I was in Terminal 3 for a United. SFO to LAX flight this morning. It was cancelled and I was rebooked 10 hours later and given a meal voucher. Subsequently, I rebooked myself on a Skywest flight at noon. I carried that voucher past innumerable fantastic-looking restaurants in terminals 3 and 1. Here I am in the Skywest terminal with three choices: ice cream, JambaJuice and Perry's. Live and learn. And let the voucher expire.
