The international sign of disinterest or being in a rush is looking at your watch. I was helping my dad out at his business, and while I had my back turned to the customer to grab something off the shelf I naturally glanced at my watch when I felt a tap and the customer said "are you about to go on lunch?". At first I was confused why she would ask that and said no, but after a few seconds I realized that society still needs time to adjust to smartwatches and the fact that looking at your watch no longer just means checking the time. Never having owned a watch before the Apple Watch, this sometimes escapes me when I look down at it. I'll need to be more vigilant about checking my Watch in front of people I don't know so it doesn't get perceived as rude. Society will need some time to adjust body language perceptions to this new technology.
