    USPS and it's services entirely needs to be revamped. The toll free number has horrible responses as it's not meant to alleviate any user stress. The people who are delivering packages DO NOT handle any and all packages properly - in fact there are multiple occasions that the delivery rep just drops the packages lazily. I am sick and tired of how USPS handles deliveries and packages. This has to change - as an agency that the public needs these people are the most laziest individuals i've ever witnessed.

    Came into the office at 4:28pm and the lady at the counter said she could not help me as she closes as 4:30pm. I went to another post office and they said they have to help me if I’m in the door. As long as I’m in the door before closing time.

    I’m from Hayward but I always come here. Customer service is superb! Excellent service! Both the ladies(maybe Filipino) are very kind, courteous and know their craft. Makes my transaction easier and not stressful even the line is long.
