I am not a dog!

[pncwho]

Still working at the fabric store. There is one customer who has been getting on my nerves. She seems nice enough when I'm helping her, but when I finish cutting her fabric or otherwise serving her, she doesn't say, "thank you," she says, "good girl!" Yes, in the exact same tone of voice you would use to praise your dog for fetching your slippers.

Has anyone else been addressed in this way? What kind of person considers it acceptable to address their fellow human beings like dogs?

I wonder if she'd get the clue if I replied with "woof" next time she said "good girl."
