I can understand why it's happening, at least:

* Don't need to purchase paper.

* Don't need to purchase or contract a printer.

* Can change the menu willy nilly.

* It's in line with the current environmentalism fad.

But that said: If the restaurant can't be arsed to provide me with requisite-free information on what god damn food they serve, I can't be arsed to provide my god damn money for their time.
