When DH and I were in college, he was about to go to the store to get some Vaseline for his roommate. The roomie was sharpening and airproofing some survival knives IIRC. Anyway, he asked the crowd in the hall at large if anyone needed anything from the store. One girl was about to make a salad and asked him to get a cucumber! He refused. He said he wasn't buying Vaseline and a cucumber at the store.
