The US Postal Service says 55 small Maine post offices have reduced their hours as part of the agency’s cost-cutting plan and 200 more will do the same in the next two years. The financially troubled Postal Service said this year it was planning to shut down some post offices and reduce operating hours at others. The Bangor Daily News reported that most post offices that regularly had eight hours have been cut to six or four hours. In more extreme cases, some post offices are open only two hours a day. Postal Service spokesman Tom Rizzo said the changes affect only counter service and people will still be able to gain access to the lobby and post office boxes when counters are closed.
