workstation on wheels

Sometimes, when I go to the hospital, doctor’s clinic or even at the Dental’s clinic, I noticed that the employees are using a workstation on wheels  when they are working. Most of the time hospitals or clinics are busy in the morning so they always drag their workstation which is cool. I remember when my son and I were in the airplane he asked me why the flight attendants are pushing their workstation and I told him that it was workstation on wheels. He was thrilled to see the workstation.
