You call for help at half past 1, says he'll be there on the run. You wait and wait and wait and wait and he doesn't show 'til half past 8. "Wish I'd called Roto-Rooter!" You call Roto-Rooter at half past 2, you're asked if 4:15 will do. At 4:15, "The van is here!" And just like that, your drain is clear. Roto-Rooter, when we say we'll be there, we'll be there.
