I just had a similar thing happen to me. I don't believe it was the guest, but the friend or family member that came to pick them up at check-out, to go to her house in my area.
I usually leave enough of a supply for my guests for the duration of the stay, plus one extra refill.
This person took every toilet roll, a complete roll of paper towels, an almost full roll of trash bags, wrapped soap, and a package of moist towelettes. Emptied the refrigerator and the snack basket, too.
I found the friend/family member wandering around in my back yard, ostensibly looking for the trash bins. Really, if she is from the city, she should know they are in the alley.
Nothing of real value was missing, though, but I feel I should change the codes on the entry, and be glad I'm not missing sheets and towels too.
I'm so glad they did not have access to the whole house !
