Your lab mixed up my photos with someone elses. Ok, that sometimes happens. Let's fill out a tracer, sez I.
No need. They mixed them up with my mother's pictures.
Golly, what a coincidence.
Yes; and they did it in the middle of the roll too. I got some of her Hawaii pictures, and she got some of mine.
Hmm. Were you on vacation together, queries myself?
Of course, says customer.
What kind of camera does your mother have?
A Nikon, exactly like mine........
