I can think of a few reasons:

- The field name implies that the primary key field is a string. This entails numerous issues (eg. How do you generate a new unique ID?) - It is not obvious that the field is the primary key. - A 'name' property on a reservation doesn't make sense. Is it the name of the person making the reservation? How can this be unique? etc.

My use of "name" was a poorly chosen example to tie to the concept of a reservation. I just chose it because "name" is an extremely common and unambiguous column in many tables.
