utmost compliment?

as i was taking care of a patient, i had to step out of the room to grab something quickly. as i came back to the room...

patient's daughter: my mom had just paid you the utmost compliment.
me: huh? (smiles at her and her mom)
patient's daughter: she said that you are most kind, you must be Jewish!
me: oh... (smiles and attends to patient) thank you, but i am not Jewish.
