Good to know.
I’m really fighting this concept that we have to let guests do as they please because any other route might result in retaliation. The guest asked to leave their bag and the host said no. The guest did it anyway…that’s combative. The guest should fear the retaliation of the host, i.e., canceled stay and bad review. The host choosing to be non combative by treating the guest with respect for the rules, the host and the guest, IN THAT ORDER, seems the way to go.
Yes there are guests who are unhinged and treating them like normal people is ill advised. This didn’t seem to be the case. It doesn’t really matter as the OP has made it clear the woman is no longer welcome in her home.
