One Hour Photo

“Your ticket please?”
“Oh, sure…”
I said, to the boy behind the counter.
“Debbie?”
“Yep.”
“Okay, your photos didn’t come in yet.”
“Huh? Isn’t this a one hour photo? I gave you twenty-four hours.”
“Yeah, but it sometimes can take a day or two, depending if we have to send them out due to an overload.”
“I see…You need to do some major fine printing on your sign then...Can I come back tomorrow?”
“Yeah, it should be ready by then.”
The boy said, in an uncertainty in his voice.

Suggestion?

The sign “should” read:

ONE HOUR PHOTO
Please be aware that
your photos may be delayed
a few days due to high school
kids handling your precious
film.

Has anyone else ever experienced this before?
