Storing bags for guests pre check-in and and post check-out?

It’s my pet-peeve when guests EXPECT you to look after their luggage for them - as if you don’t have anything better do do the just wait around the house all day!! So cheeky and entitled. I too refer them to alternatives - one of which is a locker room in a local gallery and actually free. I actually just got slammed in a review by some spoilt brats because I had to go out and was unable to take responsibility for their 3 cases… look at the details here !!
