How Efficient

Sitting in a Marriott hotel lounge during a February out-of-town trip, I looked up with amusement to see a robot shuttling a tray of food to the bartender from the hotel’s kitchen. Naturally I snapped a photo. It was the first time I’d seen a robot server in a foodservice setting. Judging by how far the kitchen was located from the hotel’s lounge, its use surely saves many human steps each shift.
