So, I find it a bit odd that people who sell food in Northern Europe (I had this experience last year in Germany and this year in Scandinavia at least) seem to handle the items they're selling with their bare hands.
For instance, while buying some ice cream in Denmark I noticed the guy grabbed the cone with his hand and a few seconds later used the same hand to receive the money I gave him... Same thing in Germany, people would grab, open and butter the pretzel I was about to eat with their hands and then handle the cash register and receive my money.
This wouldn't happen here in Portugal, since people would most often use a plastic/paper protection or gloves and/or the person who handles the food won't be the same that receives the money.
So, how does it work in your country?
