They’re very careful now about MRSA and similar bugs. Each sink has a poster showing the correct, and complex, way to wash one’s hands. Each wall has a poster about the importance of cleanliness procedures. Each bin has a sign on top: use the foot pedal, not your hands. Cleaners stalked the corridor constantly, with gloved hands. The signs, though, don’t do anything about the doctor, who whipped the bin lid open with her hands just as if the sign wasn’t there. And neither the signs or the cleaners did anything about the fresh spots of blood on the floor, under the trolley and around the bin. Signs are very nice, but they don’t do the work for you.
