Military base access

I got an Uber Eats order, drive 10 minutes to the restaurant. Food isn't ready so I wait another 10 minutes. Finally the guy comes out with the food and says to me, "You have base access, right? This is the second time we made this order, first drive didn't have access."

No, I don't have base access. So I spend another 10 minutes texting with Uber support to explain the situation. They finally cancel the order and I go on my way.

Why doesn't Uber have a way to let drivers know the location is on base before they accept the offer? Why do people on base keep trying to order food on Uber Eats? I am going to turn off deliveries in the app and only do rides.
