I’m of the mentality that you get out what you put in. No ammenities equals no/low tips. I have a ''14 Camry, water in the doors and extra in my armrest, candy/cookies/mints/gum in the organizer behind my seat, magazines behind the passenger’s front seat. Power converter under the passenger seat for those long rides if someone needs to charge their laptop, all 3 chargers, iphone, android regular and usb c. Oh, and a movie playing on my kindle that I have on the front window, posted high enough where it’s out of my view, but customers can watch easily. I get comments that NO ONE is set up like this, and I explain that it’s the customers TIPS that makes this happen which opens up the flood gates for more tips… hence, you get out what you put in. If I put in 10 bucks a week on those things, but make back 100, it’s kind of worth it…
