For a lot of people the human element is important. It sounds stupid, but having someone to answer your questions, have light (forced) conversation, and some smiling makes a lot of difference.  
  
 I personally hate it and would love to order from my phone and skip the tip.

 I'm aware/I agree. Given the economics of it though, I think the human element will persist more at upscale restaurants where price is unimportant to the patrons versus, at normal restaurants where price is important to patrons.
