Asking the question because I am curious and I am sure someone will know this off the top of their head.
Thinking about big box retail. Some checkout clerks ask did you find everything you were looking for? Some don’t.
If they ask the question and you say yes, they will actually take the time to have someone find that item and ring it up for you.
Is it really economically profitable based on that one extra item to make the checker wait?
What am I missing?
