morning glory - I think you're asking an unanswerable question, because you're looking for pure logic in the behavior of the most illogical creature on the planet - humans.
I like macaroni. I also like cheese. Yet, I loathe macaroni-and-cheese. Why? Who knows? Nature gave us humans these big ol' brains for all that reasoning and critical thinking power, and the side-effect is, we also got a lot of neuroses and contradictory thinking into the bargain.
Also, you're trying to apply an all-or-nothing explanation to it: "If you're worried about germs here, then why aren't you worried about germs there?" That's kind of like asking the jogger who smokes why they're smoking if they're obviously interested in their health, or asking the person who just ordered a Big Mac why they bothered getting the Diet Coke. If you're going to trash your health, may as well go all the way, right? But people don't look at it that way.
Besides, like I said earlier, it's easy to wash produce, so a person probably gets a good feeling when they do it.
I'll bet I could set up a box with a plain old light bulb in it, and put up a sign that says, "Do you know who's handled your bread? Studies show fresh-baked bakery loaves have 14 billion germs on them on average! Please use our germ-eradicating ultra-violet box to kill 99.99% of the germs on your bread!," and by the end of the day, at least half the shoppers would try putting their bread in it to kill the germs. Why? Low effort for a possibly positive outcome.
