The idea behind the system
The big Idea behind the telephone sna pneumatic systems is that a diner, seeing a prospective partner at another table, will be able to get into immediate and r"lvate communication with her or him. Each table has a placarded number and the liner merely uses the telephone on his or hei own table to dial the prospect. The pneumatic sj-stem runs around the walls, rencil and paper are furnished at each table tor the billets d'amour. A central station receives and reroutes the messages.
