I've Never Tipped a Man on a School Supply Order

The man stood there and said nothing. Didn't reach for the bags just looked at me. He also didn't turn any lights on his house aside from what looked like a single light fixture three rooms away so there was just a faint back glow behind him. Shocked I just blurted out, hello how are you? And he stood there and saying nothing. Needless to say, I haven't stopped in that area again since.
