Limiting customers appointments

In an education setting, appointments are free and therefore open to abuse. Students will make many bookings, which is unfair to other students trying to access the limited resource. Other booking forms offer a set limit feature in the tool to allow, for example, only one appointment per day per customer on a particular service, or even one appointment across all services per day. This would be a very useful feature in this non-commercial setting, allowing more equitable access to student services.
