Although some of these answers go back to the question, of how do you avoid dancing with people when the stand in front of you and ignore the fact that you are obviously suddenly either deep in conversation or frantically searching through your hand bag?
You say, "no thank you".
We're guys. We don't take "hints" particularly well, (and we don't want to guess). If it's unclear what the woman's intention is, the easiest way for us to find out, is to simply ask her. Most of us will get over (and for that matter forget all about) a rejection, unless the follower does something to make to the rejection memorable.
If you want the guy to ask you again (later on), you need to tell him to ask you later, when "whatever" has occurred (to make it clear for him). If you don't want to dance with him anytime soon, then just say, "no thank you" without any emotion in the rejection. If you don't want him to ever ask you to dance again, then make the rejection something he'll remember.
The rejections I actually still remember, are the couple that I received with a big smile, and one that was very rude (actually it was during a class with partner rotation). I found them all equally to be very strange, and awkward. Going forward, I never approached any of those people (even for a conversation), unless they made it crystal clear that they were OK with me. Funny thing is, the follower who dissed me in the class, actually did that, (months later), so I have no issue with her now.
Also it is hard to say no to 'nice' people, even if the dance is excruciating, so I can see why saying "thank you" early or an outright "no" might be hard. I am very wary of pointing out flaws (even really serious problems) on the dance floor as some guys take it very, very badly. In my experience, some guys will take you pointing out that it really hurts when they twist your arm/ crush your neck/ stamp on your toes as an attack on their masculinity no matter how you put it. I remember hearing an exchange a few years ago when a follower suggested that a guy might want to adjust his step size down (he wasn't giving enough forward intention for the size of step-I'd already noticed this and had spent several months doing the "I'm in fear of being broken" cat-on-hot-tin-roof tango walk). This was not well received and he spent the next few weeks in a massive strop and slagging her off to anyone who would listen.
Definitely a case of pride very much damaged. However sensitively put, some people will always take it badly.
It really isn't about pride. It's more about not wanting to be with people who don't like us.
One technique that I think is helpful for followers, is to tell the leader what they like, rather than stating the the leader is doing "whatever" wrong. I think most leaders actually do want to know what various followers like. If you tell us, then (assuming we know how) we can make an accommodation (or even a change) in our dance.
However, there is a possible side effect in communicating your preference (or complaining to the leader). The leader may simply conclude that the benefit of dancing with you, isn't worth what he needs to do, in order to make you happy. Thus he could decide to ask others, instead of you (assuming there are other people who actually do want to dance with him). It's up to you whether that is a good side effect or a bad one.
With me, I'm always looking for ways to improve, and expand the number of people who might want to dance with me, but I also know who I am and what I like as well. I can accept that some people just don't like my style. It's nothing personal.
It's a risk for the follower to communicate about issues, but guys take risks in just trying to figure out if the woman wants to dance with him. Everyone is different (and some people are jerks), but it's very likely that even a nice guy will never fix a problem he has, if no one ever tells him about it.
BTW, I have heard more than one teacher say that if the follower gets her foot stepped on, that it's possibly her fault, for not creating the space for the leader to step into.
