A smaller switch would be a terrible idea. They're already pushing so hard to have mainstream games on the console, and those games have UI elements that can only get so small before they're useless. You'd have to develop your UI around being used on these tiny screens, which either takes extra work or leaves big screen users screwed.
A smaller screen switch would basically be relegated to phone games, and all other games would lose a lot of detail to size
That's the funny part, if I'm the owner, I can do whatever I want. "It's a must"? Too bad, it's my restaurant and I want to sit here. "You're being rude to a customer" I'm being rude to this customer, too bad.
