Coupon Code One Time Use Per Customer

In an attempt to convert customers from using Skip the Dishes and Uber eats, my client would like to use a coupon code that is ONE TIME USE per customer.

For example, we have printed a business card with the code "NEWSITE" to save $2.50 on their next order. The customer would then use this coupon code on checkout ONE TIME on their first order to switch from the delivery service, to the customer's website.
