What are the most bothersome patient behaviors?

Medscape asks a group of neurologists:

The top 5 most bothersome patient behaviors from most to least were the following: no show for appointment, verbally abusive with your staff, poor compliance with medications or treatment, late for appointment, and do not know the medications that they are taking. Of the 30 items, those behaviors as well as answering cell phones during office visits and unnecessary phone calls after hours were among the most highly rated as bothersome.
