Idea for restaurant tray liners or placemats...just for you!

How about restaurants having one tray liner for adults and another for children?  It seems like there are only ones for children or those promoting contests.  How about a tray liner for adults with a calendar, area for notes, crosswords, etc.  In addition, there could be tray liner printers in restaurants to print liners on-site.  These liner printers could update with the latest news from the internet plus give updates on news at the restaurant.
Possible Start Building Blocks –

• Existing concepts for placemats, tray liners, double-sided printing, on-demand printing, on-site printing, newspapers, etc.
