This is the worst postal company ever invented. The mailman delivers mail when he feels like it and most of the time won't deliver at all. A couple of time I will see him parked in front of someone house just having a conversation for minutes. Sometimes others that are in training just won't care in place mail in your box that is of others just to get the job done. # THEYARETHEWORST#
