Fresh produce worker: Hi Mam! Can I help you with anything?
Me: Yes, I need organic rasberries, please. (he was in the way)
FPW: Oh! You want those... Why do you think they are different?
Me: Less pesticides.
FPW: Not it. The difference is the price. Pesticides are everywhere, in the water, in the air, your rasberries are the same, you're just paying more for the same thing. We (produce workers) laugh at customers like you for beign so gollable!

I didn't say anything more.
What would you have said?
'Try some, you'll get smarter???'
