I could understand the low ratings from other people because lines do get long sometimes. But the handful of times I've been there, there's an extra employee who delegates the line. ie. Asking people "what are you here for." Just to make sure you're in the right line or can show you an alternative to TRY to make your experience quicker like those who can use the kiosks.
Also suggesting other packaging that could be free (priority mail boxes are free with who already with prepaid labels)
My only complain or suggestion is that I wish they provided more shapes of those free boxes. I've lived in other states & other USPS a provided all sorts of shapes like a shoe box shape (rectangular that could fit shoes + shoe box) & etc. other than that I know the employees are hard workers.
I've also called this location because they missed to pick up my package that was scheduled for 12pm. I got homes round 3 & noticed package was still there, so I called them & mail man came back in 10 min just for my package!!! Wow. Rang my doorbell & was courteous. even offered him a water bottle (it was 100 degrees out)
