Emailing a lunch appointment?

Q.
Do you make lunch appointment often that you would consider emailing it? Or use an App?

A.
In the busy schedule of today's life, meeting up a client over lunch is inevitable.

However, unless the lunch is for the enjoyment of the food and not business, you won't want to drive in the traffic to first reach the destination and next to wait for the food.

Hence, the idea of emailing a lunch appointment. The idea is you make an appointment with your client over lunch and the delivery will send the food to which ever the destination. The choice of food would be picked by both the client and you. Either you go pick it up yourself ie at nearby kiosk or you pick it up on the way to your client's place.

The Application would have an invitation to the client like in whatsapp. When the client register as yes! Then the food choices appears. By making selection on choices of the food, the bill goes to the person who initiate the appointment.

Then, the delivery mode is decided, either by own pick up or delivery (limited to a geographical area).

Payment can be made by cash or online e-banking.

What do you think of the idea?
