We understand parking could be difficult in Los Angeles.
However, there are plenty of hidden options that you can use like: tell a valet guy that you’re just picking up or dropping off the order (they let you leave your car for free), park halfway of garage doors, look for green meters and leaving cars etc. Be smart and try to avoid illegal parking (especially, near red curb).
DON’T ask a customer to come down to pick up his/her food (unless noted by the customer).
ALWAYS try to deliver to a door.
Customers pay you for SERVICE. Please, give it to them.
