If the mail were delivered every two days, we would have the opposite problem. We deal with some legal documents that require us to meet given deadlines. We could have a problem If we received those documents in two-day intervals.
The other issue is the people waiting for their cheques. We saw what happens when there's a hold-up just for one or three hours in a day. If people received their cheques two days later, they would be affected. Although people have the option of direct deposits, some expect to receive certain documents quickly, and they are literally waiting by their mailboxes.
So that would not be a solution for us right now. There may be less mail, but the fact remains that people want to receive their mail at the same rate, and it's important for us to receive some documents quickly.
