Who was the speaker?

Hello, I was once an airline hostess. Now I’ m on my first bus trip and I’ m quite amazed at the services offered during the trip. Included are meals on the way, rest rooms, public-address announcements and a uniformed hostess. Just now I introduced myself to the hostess on the bus, and we compared experience on air and ground travel.
   At lunch time, she gave out menus offering a choice of sandwiches. As she began filling orders, she found that there weren’ t enough egg-salad sandwiches. She quickly went to whisper to the driver. The bus soon stopped. The hostess dashed to another similar bus that was all the time following ours, and soon she returned with a box of egg-salad sandwiches. As she passed my seat, she asked, "Could you do that on a plane?"
