I remember my first two days during peak they had me doing smalls and thinking to myself, "hey, this isn't too bad!" Then on the designated training trucks (one tanker, 2 country routes) that probably did ~500 day and still thinking this UPS gig wasn't so bad and looking forward coming in. Then I got moved to the middle of a different belt, 4 trucks doing over ~1000 a day and getting overrun and buried so quickly even supervisors were saying "yeah, it's been a while since I've seen it this bad." So yeah, it doesn't take long until "can't wait" turns into utter, unspeakable dread.
