> Examples: The buzzer for restaurants, why can't it have a screen to display menu, or let your preorder? those things are dropped, lost, chewed on by children for 8 hours a day, etc. they've got to be as cheap as possible. also who'd stare at the shitty little screen that's nothing but ads, when they could stare at ads on their expensive slightly larger screen that they carry around all day? if you want really a menu, the host will be thrilled to hand you one. there's a box of them under their station. > At a restaurant, why can't I see the most ordered 5 items and have to go through pages of menu? because then they'll have fewer opportunities to upsell you on more expensive dishes, and alcohol. > Similar idea for supermarkets: why not have a giant screen at the entrance showing most bought products, interesting product pairings and other data that may be useful? who cares what's most bought at the grocery store? knowing that my store sells ramen by a truckload doesn't get me buying anything the store wants to actually sell.
