That's what one of the regular carriers said to me yesterday. This is undoubdtedly true, though with yesterday's volume of mail (my route actually set a record for volume yesterday... with me on it) it almost wasn't fast enough.
Nonetheless, a few weeks ago if you had suggested that I would sort, case, and deliver almost 4,000 presorted letters plus I don't know how many flats and unsorted letters, 3 certified letters, 34 parcels, make a parcel pick up... and make it back a half hour before the outbound truck... I would have laughed at you.
They even offered me an LLV yesterday, but I used my Passat wagon. Just color me bad, I guess.
