Guests requesting things that are not listed

Hi I’m super annoyed we’ve had a relatively smooth run for the last 9 months and this last month it’s as if every guest is from hell. To start off the requester kept asking for a discounted rate to match what she wanted to pay and not realizing it was probably a scam I accommodated the request.

This person is now complaining that we don’t have scissors along with other supplies in the unit in the unit. I can’t recall scissors being in any unit I’ve ever stayed in and never had a problem with it. We also never claimed to provide essentials for the unit although we do have dish liquid and other items that are needed in the kitchen and bathrooms. They are not happy with what was provided…Is it really the hosts responsibility to cover cleaning supplies, paper towels, bathroom and kitchen supplies for the guests? Usually when I stay in airbnbs myself and these items aren’t available I purchase them for myself?? Am I wrong in the believe that you rent as is and add whatever else you need for your stay. It’s not a hotel.. if you wanted shampoo and soap you should have paid for a hotel no?
