If you don't mind breaking immersion and want to min/max the affection with your current companion (useful early as you only have one companion for quite a while as many classes) you can hit Escape to break out of a dialogue if you happen to choose a dialogue option that your buddy doesn't like. The vast majority of dialogue choices have zero impact on story, quest outcome or LS/DS gain, and really only exist to allow the player to role-play and/or gain/lose affection. Bioware's misleading dialogue wheel of randomness makes a return in many of the quests, and the option you thought your companion would love turns out to be the opposite of what you'd expect some of the time.
Later on I found myself listening to each new section of a dialogue, and then picking each option one by one, breaking out of the dialogue and spacebar spamming my way back to where I previously broke out. It doesn't take too much longer and you can avoid a lot of headaches if you're a min/maxing player that wants to get your companions leveled up without buying tons of gifts.
Bear in mind that most companions, for the most part, favor either LS or DS options, but will also sometimes prefer the opposite of their normal preference. For example: the IA's first companion Kaliyo generally likes to cause mischief and mayhem and prefers DS options, but makes an exception for helpless aliens or LS options that screw over the Empire. You can't really avoid getting screwed one way or the other on these, as there's no advantage to being "gray" and you're going to want to commit to either LS or DS if you want to get access to items on those vendors as early as you can.
