take a break ( stop what you are working on )
The USPS does borrow money from the US Treasury when the Postal Service runs a deficit. However, the USPS is suppose to break even, so the borrowed money will eventually be paid back through higher postal rates. The USPS actually ran surplusses in the 1990s, however, lately, it has had to raise postal rates almost every year to break even. The government also pays the Postal Service almost $100 million a year to cover government mailing costs.
USPS Holidays are those decided by the government when mail will not be delivered. These can be found listed on the USPS postal service website or at an USPS site.
There are multiple online websites where USPS locations can be found. Good websites which can be used include "USPS Get Started" and "USPS White Pages".
When you throw something in the water it will not break, only get water logged and stop working.
