Just got a shopping delivery. The driver arrived late and he was banging on everything he could on his way from the van to the house, without even saying Hello he literally threw the crates on my doorstep. I asked him to bring them inside, he pushed them violently on the side, huffed and then brought them in, he was suddenly walking very slowly and looking around my living room, I unloaded the shopping, he then threw the crates again outside and left without even a bye-bye. I live in a two bed terraced, we have nothing of value (not even a TV), I am not British and I spend most of the days home alone with the baby. I understand that is a tough job and it's late, but his behaviour really shook me. Should I complain?
