Stupid Customer

So today I'm standing up at cash when a lady comes up to me, she's holding a baby, and she has a very thick accent. She looks at me and asks:
"yuh haff eeah cleanah for kits?"
I automatically think of ear mite cleaner for cats. Would make sense, yes?
So I double check.
"Ear cleaner for cats?"
She looks at me like I'm utterly stupid.
"Noh! Fohr Behbehs!" and she jiggles the kid in her arm. For babies.
I look around the store. We have a large Macaw in a cage right beside the woman, she walked past a cage of kittens to get to where I am standing.
"We are a PET STORE, ma'am."
"What ees thaht?"
I sigh. Actually?
"We sell animals, ma'am."
She looks around the store, "animals? Really?" she looks back at me like she thinks I'm lying to her. The Macaw chatters.
"Yes... really."
She leaves.
I look at my coworkers who were at cash with me, they all burst out laughing, all I can do is shake my head.
