Allyou can do is do it.
Offer it first to just a few loyal carryout customers. (offer them 20% off???) Make sure you have a couple of people available to drive, but they need to be doing other things too, like helping with dishes, boxes, cleaning (see ‘driver responsibility’ thread)
Do the select delivery thing for a couple weeks, then evaluate. If it’s not working, make a major change in process, and continue the trial. OR, bag the whole idea (pun intended–delivery…bag… :roll: )
There’s no real secret–get the food out as quickly as possible and as tasty as possible. BUT, the customer pays 2 prices for the service, and it IS a service, not a requirement on your part–They pay a delivery charge, and it will take a while. Carrout is second priority, dine-in first…then delivery.
Avoid a blanket guarantee on time. You will have some arrive late if you promise 30 minutes all the time, and it will cost you. By working with loyal customers you’ll have a learning window, with allowance for goofups, and they’ll feel special for being part of your expansion of service. Make sure you treat them right after this trial period, no matter what happens.
