I think it was Afghanistan that I discovered that not all produce is the same, they had some honeydew and cantaloupe that I'd happily run the Dallas Dash again for, it was out of this world, and it definitely started me down the path of wanting to grow my own produce so as to be able to control as many of the variables that result in quality as possible.Those produce rules vary quite a bit. In Spain they don't like you to touch it and they choose for you, but in Portugal it's fine.
I will just add that the quality of produce here is freakin' unbelievable compared to what you get in most of North America (and yes, that includes Whole Paycheck). Gigantic, beautiful red peppers for example. But also the flavors. Fruits that actually taste like what their appearance would suggest rather than generic fruit flavor. The most amazing raspberries I've had since my dad's berry farm when I was a kid. Lakeland-style citrus that tastes like orange blossoms. Grapes are so grapey they almost taste fake. Snozzberries that taste like snozzberries. And all very cheap in comparison. Of course there are trade-offs, like stuff you just can't get, or imported foods being more expensive than you'd expect.
