It is very probable that there is more to this scenario than the information we have. I do have to say that if the guy was having a tonic-clonic seizure he wouldn't be yelling at the doctor about his choice of medication. He would be unable at the time and for a while afterward.
We could make up all sorts of scenarios.
I do have to say based on my personal experience and the shared experiences of others with epilepsy there is a lack of knowledge and a lot of prejudice about the disease and that has made many "professional's" (medical and non-medical) make decisions based on fear, bad information and wives tales.
