A few days ago, our family splurged and enjoyed a MacDonalds lunch. As usual, we all got water. For us, the big reason is saving $5 or more.
This was the first time I had seen cups specifically for water. Possible reasons for this are:
- To keep the customers honest. If another customer saw someone filling their water cup with soda, the fraudulent filler might feel guilty.
- To make the water drinker feel self‐righteous. They might want to brag that they are drinking a healthier drink than others.
Do you have any additional ideas why they may have done this?
