On a more serious note...

tomorrow I'm going to try to commute to work. If by chance I don't get on 1 of the 4 (i know the min is 2 documented) I'm obviously going to use the ol' commuter clause. Now, even if I pull the clause on Xmas eve, I still have to keep trying to get to work right? It's not like they just figure I won't be there for the rest of my trip....?
