Many leave you shampoo, conditioner, body lotion and soap. Some now have a dispenser for shampoo and conditioner instead of the little bottles and I have NEVER been charged for them.
I have stayed at one hotel in my whole life that had the refrigerator bar you had to pay for and I did not touch it. They did not have sensors on them either like in Vegas.
Okay, I forgot about the little free packets of coffee that most hotels provide. I usually don’t use those and go down to the breakfast area in the morning.
The only hotel where I saw a refrigerator filled with drinks and snacks was a Hilton. And Hilton did not have a breakfast area. It was pretty obvious from the signs in the room that anything I removed from the refrigerator would be charged on my bill. So I didn’t take anything from the refrigerator.
