I'm just kinda interested to read what everyone has to offer for their passengers.
I myself have:
- a USB charging unit that caters to Android, Iphone & USB-C phones (http://www.powapod.com/)
- a CarGo box with some free snacks/stuff and some you have to pay for (https://getcargo.today/)
- free candy
Do you feel amenities increase your tips? If so, which specifically do you feel increase your tip chances?
