When I was booking a flight on the Air Canada website (which was relatively easy, considering how hard travel agents make it sound), I noticed that you can order different kinds of in-flight meals. They included:

• Asian Vegetarian meal
  
• Bland/Ulcer meal
  
• Child meal
  
• Diabetic meal
  
• Fruit platter
  
• Gluten free meal
  
• Hindu non-vegetarian meal
  
• Kosher meal
  
• Low calorie meal
  
• Low cholesterol meal
  
• Low salt meal
  
• Muslim vegetarian meal
  
• Non-lactose meal
  
• Oriental meal
  
• Regular meal
  
• Vegetarian (lacto-ovo) meal
  
• Vegetarian meal

Wouldn't it to be cheaper and easier to put a big disclaimer button on the website that everyone has to click to continue that says,

ALL FUSSY EATERS MUST BRING THEMSELVES A SANDWICH.
