I have a theory about why Jerry's date didn't taste the pie:
Maybe she had a similar incident like George (pissed off the cook) and was afraid to eat the pie because it might have been tainted. This could never be proven since they never showed a scene where she pissed anyone off..Ah well to hell with that one..
