I think I just realized what McDonald's will be like, 20 years from now:
"Hey Sirtana, I feel like McDonald's today.."
"Do you want me to drive you to the next McStation, Tosh? Same meal as always?"
"Do you want to use your Google-Account for payment?"
Ten Minutes later the car stops near a small box. The box opens and here is your ordered meal. You take the food and eat silently while Sirtana drives you home.
