What does the highlighted part mean in the following passage please?
In Japan, there are strict norms involving the exchange of business cards. One person presents his or her business card with the writing facing the recipient, who looks at it for a moment and asks a question about some of the information on the card. The question may be irrelevant, but it tells the giver that the recipient has read the card and acknowledges the person and his or her company. A Japanese executive who receives a business card and does not take the time to look at it and ask a question would be considered deviant.
