At LAS, they started giving out meal vouchers for Rouge YYZ flight as soon as they announced delay over 2h.

Unluckily for me, this was also at the exact same time that I was approaching the desk to get my baggage offloaded so I could preserve my LH F connection by flying to SFO rather than YYZ. I declined to wait for the voucher as I had to get my bag (in a separate building) and then recheck it onto UA for a flight in the following 90 mins... It was a crazy day !
