I agree that it’s a long trip, but the distance a candidate is willing to travel for an interview is on the candidate, not the district. Regardless, I still wouldn’t tell anyone off. What’s the purpose in that? If the goal is to get them to change their ways and inform candidates in the future, I think that can be done calmly. If the purpose is to express your anger, that just seems unprofessional. You never know who knows someone else, even four hours away. I wouldn’t want to earn a reputation as someone with uncontrollable anger.
