Lazy mail carrier thought it's ok to state they couldn't deliver 2 of 3 packages to the front door because there was no access meanwhile they delivered the regular mail in the mailbox right beside the front door. Then almost 2 hrs later he enters the third package as it couldn't be delivered because of the weather..... I'm reporting him, and found as far up the chain of command possible because this isn't the first time and I'm making sure it's the last
