Automated ordering

Today I walked into a restaurant in San Marcos. There was nobody in the front of the restaurant. Not employees, not customers. I looked through the service window and there was someone in the back cooking. I went ahead and put in my automated order, as two other customers walked in. They asked me what they were supposed to do. I said I don't know. I don't work here. A minute later, an employee walked out of the restroom and there was finally someone in the restaurant and had literally been 6-8 minutes. In a self automated dining room, where I punched my own order into the screen it closed out the transaction by asking if I wanted to leave a tip lucky for them I was starving.
