true customer tales

An old gal has called me 5 times in the last 15 minutes asking if we buy books.
When I answer in the affirmative she asks if we buy cookbooks.
I say yes, she thanks me and hangs up.

How would Miss Manners tell her to stop effing calling?

CALL #6

old gal:
Hello, I know I've called before, but would you buy cookbooks tomorrow?

me, for the 6th time:
Yep, any day before 4pm.

old gal:
Oh, thank you!

me:
