The Great Cucumber Debate

I went grocery shopping and the woman at the check out asked me what I was planning to do with the cucumber.  This caught me off guard, more so as the rest of my shopping (meat, lettuce, spinach leaves, carrots and celery) seemed to lend itself to the idea that I might be about to make a salad of some sort.

She wanted to know how I was going to eat the cucumber.  What sort of question is that?  When I advised her most of it was going into the salad and the rest might be used with cheese and crackers she found this puzzling and told me that was a foreign thing to her and anyway most people don't buy cucumbers. Whole thing was just bizarre, do Americans not eat cucumbers? Am I the sole cucumber seeker in U.S. super markets?
