Gringita mistakes

We went to the store to get some sandwich supplies in an effort to save some cash. In Peru, they sell a looot of jamon (ham) and they also sell other sandwich meats and just call them jamon too. We ordered turkey , leaning over across the deli meats ¨pavooo por favor¨and he picks up ´jamon de pavo´ ¨no no, no jamon!¨we point to the big turkey in the glass in front of us...¨un kilo?¨ we look at each other neither of us really sure how much a kilo is, but it seems okay. So he starts slicing, and slicing, and soon there´s a looot of turkey so we yell over for him to stop. A half a kilo and we´ve got enough lunch meat to last a week. We grab the rest of our items, bread, fruit, lettuce then go to the check out. bread- 10 cents, fruit 2 bucks, lettuce, 50 cents, turkey-11 bucks...!?!!!!!!!!! wait..too late, we´re checked out and paying up before we can even figure out how to say stop!
gringita lesson learned.
