Question: how long does it take mail to get from shreveport to baton rouge?
Answer: New Orleans to Baton Rouge, 1 or 2 days. But, say, Luling to Shreveport? 3 days or possibly 4. At my workplace, we've been trained to the USPS line, that First-Class is “typically 3 to 5 days” (to anywhere in the contiguous US), and then we offer the caveat that only with Express Mail does the USPS give a “guarantee”.
