A postmaster would have zero clue whether or not mail was delayed. Mail is delayed at point of induction not at a delivery facility. There is no square footage available at a delivery facility to store anything. It usually sits in trailers outside processing hubs heavily secured. Delay of mail contravenes not only the Postal Act but several labor agreements as volume counts for route restructures are done in delivery facilities. A National delay of mail grievance is easily worth multi millions of dollars in unscheduled overtime settlements.
These fukkin lawyers making up bullshit about mail have no clue how mail is processed. If they did, they would very quickly shut the fukk up.
