Guests have arrived today, they have stayed lots of times before. I have explained to them they can have a bath (which has a shower attachment) in the main bathroom or a shower in the ensuite on my room. There is a seperate shower in the main bathroom but it does not work as the shower head is broken - they have turned up today with a showerhead which does not match my bathroom presumably with the intention of fixing it. BTW - they have expressed their unhappiness about the bath situation before. I actually don't want the shower fixed as it is the only place for the cat's litter tray to live.
Am IBU?
