Trying to find breakfast

So El Paso has Mexican restaurants all over the place.

Why are none of them open early? Almost everyone that works has a typical 8-5 / 9-5 schedule, yet if i want a nice, hot chile verde burrito, chile relleno, or machaca burrito with a coffee or horchata no one is available to provide that service earlier than 8a.

Now I have found some restaurants that are open at 730a, but they don't answer the damn phone. I want to be able to put in a phone order, at least, that way it's ready by the time I get there and I can make it to work on time. I pass by the restaurant I wanted to order and there is no one there-

I dont understand why this is an issue. So why not answer?

Why don't people that work at these restaurants want to do their jobs?

Edit: clarity - "everyone" as in humans working
