I found a boy who looked a little older than me, and I offered it to him, saying, "I found this on the floor as is, there are several in the other aisle," in an effort to help him out.
He looks at me a moment, and responded with, "So I suppose you just want me to give you it now, huh?" in the most flat, agitated voice ever.
Really, I was so flabbergasted I didn't say anything, I just set it down on a shelf and left the store. I felt really embarrassed, too.
