I live in Louisiana. We had a few online friends come and stay with us a couple years ago - from New Zealand.
Going shopping with them was one of the high points OF MY LIFE. Absolutely HILARIOUS.
'You color code your cheese... but not your money?' (my fave!!)
'CHEESE IS NOT ORANGE.'
'Do you people actually COOK anything?!' (after noticing the ratio of isles of packaged and processed food versus fresh meat and veggies)
'I WANT. ALL. ALL OF IT. I WANT. NOW.' (when they saw the multitude of frozen confections)
'They keep the eggs in the refrigerator?' (was when I first found out that they're sold off-the-shelf in other places)
'Don't you have any laws about this kind of thing?' (when they read the crazy list of food additives we have in damn near EVERYTHING)
and on...and on... when taking guests shopping at Wal-Mart is one of the highlights of their visit (for both parties), you just *have* to laugh.
