I have to second Hal, I haven't JS'ed inter-island for awhile. You can't go wrong going to the counter and cover your bases for TSA.
For long gone, as far as having a problem with feeing you weren't treated as nice as you wanted:
1)As HAL said, anyone can have a bad day. Keep in mind you might be upset because that Captain wasn't nice enough to you. Perhaps that Captain just got bad news from home, their child might be in the nurses office, or any other many reasons why. She could have been preoccupied with anything to prevent her from normal courtisies. It's a poor criteria to judge an airlines quality of overall jumpseat service.
2) Generally speaking, and I'm not accusing you, but you get what you give. It is possible you weren't as nice as you think or perhaps you said something innocently enough and she misunderstood it. Point is the situation could be any number of things that don't warrent pointing fingers.
3) If you got a free ride, the correct response is to appreciate it. period.
