I'm not looking for startup ideas in this domain, I was just wondering "in general". If the PC + printer is already there (surely it has to be for accounting, etc.) why have a fax.

But ok, if the fax and the phone line cost next to nothing and it "just works", then sure it makes a lot of sense.

A lot of these restaurants _do_ have a PC + printer in a back room or office somewhere. If the restaurant is owned by a group (or small chain), that setup may only exist at one location.

They can (and do!) put the fax machine right by the kitchen.
