How do I (28M) make a first date go well when I have no intentions of having a second date?

So this is kind of a jerk question in a way. Back when I was single, but more frequently now that I'm in a committed relationship and still active on dating sites (to find platonic friends), I end up on dates with people I don't intend on seeing again. Whether it's that I don't find them attractive, we don't have very much common ground, I've been informed that I'm going on a date, etc.<br><br>I (and my partner) find that it's more polite and less awkward to still go on said date (especially if the only reason is physical attraction), so I want to make the date itself enjoyable, in spite what my true intentions are. I don't want them to feel stupid/scared/depressed, etc, and I also don't want them to feel like they wasted their time. <br><br>What are some tips on what I should do to make it enjoyable (besides being respectful) on a first (and last) date that is supposed to be romantic in nature?<br><br>*Edit: just to clarify. I'm asking for advice about how to make the first (and last) date enjoyable, NOT how to find someone I actually want to see again, as that is out of the scope of my question.
