Denny’s - I never have to wait for orders and the main location I deliver from gives me free Diet Coke, even though I always offer to pay.
Raising Cane’s - they’re always “order and pay” but the customers tip very fat for short distance deliveries at the location around the corner from me. Average accepted order is around $12 for 3-4 miles total
Taco Bell - some locations are horrible but almost every location in my area are great.
Most family owned Chinese/Thai/Vietnamese/sushi restaurants in my area. Too many to name but they’re always on point. They’re friendly as well.
Freebirds - fat tippers and the order is almost always ready when I get there.
