Really absent-minded tenants

I've had regular problems with people who don't take their clothes out of the dryer here, but this one sets a new record. Back on Tuesday or so I had to do laundry. Someone had a load in the dryer when I went down, but the washer was open. When my load was done washing, the dryer had shut off but the clothes were still in it. I gave them an hour, then pulled them out of the dryer and put them on the table so I could dry my clothes before it got too late. The next morning the clothes were still on the table. Today when I went down to put a load of sheets in, the same clothes were still on the table, shoved back into the corner. Monday if they're still there I'm going to call the landlord and let them know.
