Google announced on Google+ a new search feature that allows you to quickly calculate the tip you should give after your dinner date.
The default tip is 15% with Google's tip calculator, which you can easily increase or decrease based on your perceived value of the service. You can always split the tip by person quickly.
All you need to do is search for [what's the tip for $X] or [tip calculator].
I bet Google's searches per day spike like crazy. Okay, I am kidding. But this is indeed useful. You can now ditch all those apps you use.
