The Grocery Store Pundit

I've been doing more comics in my sketchbook lately. This one is about yet another weird encounter I had the other night at my local Albertsons. It seems like every time I go there, I see something weird. I did not make any of this dialogue up...these are the exact puns the rather hammy cashier used when I got up to the checkout stand....

I hurriedly left the store with many questions--exactly how many grocery puns does that guy have in his repertoire? Just what is the appropriate response to an unexpected barrage of food-related jokes? And why is it so hard to control my face during awkward situations?
