Question pretext
First, I am going to ask about how much you spent on already prepared food. This includes food purchased, for example, from chop bars, restaurants, and wayside stands.
Literal question
In the last 7 days, how much did you spend, in total, for yourself and others on koko and koose? [NOT JUST CONSUMED, BUT PURCHASED IN LAST 7 DAYS. READ EACH LINE, AND RECORD ANSWER FOR EACH, EVEN IF ZERO. IF DON’T KNOW, PERSUADE RESPONDENT TO ESTIMATE. DO NOT OFFER RANGES]
