This fruit juice vendor has taken steps insure his straws’ cleanliness by elevating and separating them from the rest of the ingredients. What does this say about other ingredients’ need to be separated/elevated/clean? What is it that would make the straws “dirty” if they were placed on the same table along with the other ingredients? Is the proximity to other ingredients, proximity to the road, or another factor altogether that classifies something as being at risk of becoming “dirty” or otherwise contaminated?
The straws could also serve as an informal marker of the business’ success for the day, with the less straws left in the cup, the better.
