<human>: This is a minor TIFU in the grand scheme of things, but it's still making me laugh.  

Earlier in the week I was shopping at the little family-owned grocery store nearby, and I brought several items to the cash.

The owner gives me the total and I thought that he said "$4.25" so I gave him a five-dollar bill.  He then says: "Do you have 25 cents?"

I think that he's asking me this so that he can give me an even dollar back in change.  I am quite sure that I don't have a quarter on me, so I reply: "No, it's OK thanks." 

The owner kind of looks at me funny, and says: "OK Kangar, you can get me next time."

I am confused by this answer so I look at the cash and the amount owing was actually $5.25.

Can you provide a brief overview of the text?
