In three weeks I've been helping, I haven't had this happen before. I had two packages to jump. One I could drop off, one had to be signed for. 30 seconds at the door and no answer. I'm told I just have to do "deliver, front door" on the one I can leave. NonDel, NotIn, 1st attempt, on the signature pkg, then scan the notice form. I got the scanner ready to scan the notice and as I was filling up the notice, guy comes out. I hit the pen button, got him to sign, keyed in the name but when I pushed the check button, it beeped and won't close out. The driver somehow got me out of it without having to go back and have him sign again, but I don't know how. What did I mess up this time?
