We had many times mentioned to Scott about deposit and payment of utilities when he made his reservation. And he wrote several messages in which he confirmed that he understood and accepted both to pay for utilities and deposit. The deposit is also mentioned in AirBnB so anybody can see when they consider booking. Guest always gets the deposit money back if there is no damage in the house after they leave. In fact there were some items broken during Sccot's stay, but we did not charge him for that.
About utilities, the reason we charge for that is because guest then can decide if they wish to save energy by turning off e.g. air-conditioning at night and when they are not in the house. Some guest wish to do that, while others don't care. If we did not charge for utilities we would have to take out more in rent, and we want to avoid that. Staff reads meters for consumption of electricity and water before and after guest's visit, and we send them photos of meters to give them a chance to check all. We never add anything extra, only VAT and a service charge to the community, which we have to pay outselves. I Scott's case, we explained this carefully, and I gave him some idea about what utilities could be before he arrived. He saw this and accepted but still complained. In fact he and his friends used a lot of energy. In spite of this we gave a discount to show our good will. He also complained that guest have to bring their own golf clubs, instead of borrowing our private clubs. Why he didn't mention that there were no tennis rackets available is beyond my comprehension. Of course guests must bring their own leisure equipment. If we left blubs and rackets to guests, these would be ruined in no time. In short: Scott is an inexperienced traveller but he will probably learn as he grows up.
