Cape May - On Monday I was screamed at ,by a customer, in the PO for not standing ON the red line, I was behind it. On Tuesday the red lines were gone (protesters protested I guess) and there were squares on the floor saying " Please Stand Here". I did, but I was now 6 feet from window. My arms are not long enough to hand my package over the counter. I feel like I just can't win !!!.
