I work at a large employer with 150 employees and no real cafeteria. So there a food truck makes sense. They only do 1 hour at our gate. Quick money. Plus fastfood is a 10 minute drive so a captive audience. They just need to be reliable. Otherwise I pack a lunch. So other use cases are weird to me. I can see festivals. But the food trailer out front Lowes. Who eats there? I rarely see customers waiting...
