I am a senior citizen as is my husband. We go to this location several times a month. Since restrictions were in effect about mask wearing, these employees, one a stout man and one an older woman never never never have masks on..............this is disgraceful. No shield on the window area to prevent touching. Why is this? I would say something to the older man, but he is miserable.


Closed for lunch hour during the week, the time of day when most people can get to the post office. Today I watched a newer model Mercedes speed into the parking lot, crossing over several parking spot lines which caught my attention as I do not like when people drive fast in areas where people walk and pull out of parking spots. As he passes by me I see he's also holding a cellphone to his ear, another thing that bugs me, then he pulls into what at first appears to be a handicap space. I give the benefit of the doubt, but as I'm approaching the post office I watch him get out of the car, he looks healthy enough. Then I notice, it's not a handicap spot, but designated for the Postmaster. OK, maybe there's a postal emergency I think to myself sarcastically. So he goes in the back door, I go in the front to see that the window is closed up. Another man waiting tells me, "they are closed during lunch hour now". I see it's 12:51, leaving 9 minutes till they re-open. Before that time, we look through the door to see that the window has been opened, so we go in. The presumed postmaster says to us, "I still got 10 minutes of lunch break, what do you got, is it something easy I hope?". Seriously? I don't know if the stamps the customer said he needed was considered "easy" enough for presumed boss because I immediately walked out disgusted before it was my turn to see if my package fell into the "easy" catagory or not.
