What is the answer to this riddle in BA? I feel embarassed because I have been here too long to be asking the question but I seem to get irritated looks from clerks regardless of what I do and I have recieved contradictory information from local friends. In the US the clerk bags the groceries all of the time. It seemed to me for a while that this depended on the quality of the store here. I thought that the higher end stores like Disco would do the bagging for you and the others like Coto or Norte would be self-bagging. That seemed to be the pattern that I saw when I was living in Recoleta. Then I moved to Palermo and I noticed a different trend. It seemed that the women were bagging and the men weren't. Then I thought that since this is a "machismo" society that maybe the women felt that they should do there own bagging. Then I thought that perhaps they would only feel that way if the teller was male because I saw an older lady in a very long line stand there while the girl who was helping her took 2 years to bag her collection of a million items. Then I thought that maybe it was an age respect issue and maybe older people didn't have to self-bag but younger people should. Recently I saw a couple of guys making a huge purchase and self-bagging in Disco and I realized that most Portenos live with their families and guys usually make small purchases and don't necessarily do the "family" shopping. Maybe this was the reason why I hadn't seen many local guys bagging their own things. I decided at that point to start unilaterally self-bagging whenever I went shopping for groceries. I usually don't go for delivery because I don't like the idea of my frozen things sitting out and thawing while they are waiting to be delivered and I also don't like having to stay home and wait for the delivery guy to bring the stuff. Well, a couple of days ago I was in a Disco in another neighborhood and I started bagging my things while the girl was ringing them and she looked at me like I was crazy for doing it. There always seems to be some kind of new grocery ritual to learn when you are in a different country (in Austria and Costa Rica you have to purchase the plastic bag) and it is about time that I learned this one.
