@Joanna85 i agree totally, and I would probabbly lock my thermostat, next. Once in a while, sadly, there are the kind of guests that are out to take it all. I used to offer a courtesy fruit basket, but few guests decided to eat fruits all day long, since i always replenish them. That freebie was gone. Also toilet paper and paper-towels: big waste, some guests use one huge roll of toilet paper in one day, but when i decided to put only one roll every 5-6 days, i found they are using paper towels from the kitchen, rather then buying their own supplies if they need more than what I put out. Meanwhile I find unused toilet paper in the waste basket, just to "decorate" the trash, not sure... I know it might seem like counting pennies, but i think it's unreasonable to use a huge thick toilet paper every 1-2 days (for 2 people). Thus i made a new rule: long term guests (a week or more) must provide their own supplies. And one load of loundry per week is to be made by each long term guest.
I guess, slowly, slowly, i will keep cutting down the amenities, but sadly the good guests get to suffer from the experience we have w "takers".
