Money Returned

About a month ago a lady borrowed $5. Today she came in and brought me back my $5. Then she ordered an ice cream cone. Then she went off about how she hates stale cones. I assured her that we don't have those. Then she ate her ice cream. Then she wanted to tell me more about stale cones and how at one place she had to eat her ice cream off a stale cone. I wanted to tell her that I didn't care and sometimes I like stale things, but I was scared she might ask to borrow more money.
