@Anna-and-Zach0 I can't see your listing but you need a clear list of rules
an open fruit bowl is an invitation to help yourself
if you Provide tea and coffee (I do) it's up to you to provide milk or creamers suggest you buy individual ones
keep an area in your fridge for their stuff and close yours in plastic boxes
about the carer you have to be totally clear about visitors especially using your machines , if they break one you are not covered by insurance
Relatives visitors and even careers are " visitors" guest need clarity of your rules before they bookgood luck
