A lady named Mary from California flew to Japan, in her favourite jeans and a casual jacket, to give her first speech. Fourteen hours later, four perfectly dressed Japanese gentlemen greeted her at the airport. Smiling and bowing low, they handed her their business cards. With her bag in one hand, Mary took their cards with the other. She thanked them, glanced briefly at the cards, and put them into her jeans pocket quickly.

When the five of them arrived at the hotel, they invited Mary to tea in the lobby (大厅). While sipping tea, the gentlemen presented her with a small gift which she eagerly opened. She was thrilled with the gift and shouted excitedly, “Oh, it's beautiful！”

At this point, the four Japanese gentlemen stood up and, bowing only very slightly, said “Sayonara” and left immediately. Poor Mary was left astonished. What did she do wrong?

Everything! Her jeans were the first gaffe. Even if you're coming off a bicycle in Japan, you do not meet clients (客人) casually dressed. The second mistake was Mary's handling of their business cards rudely. In Japan, the business card is one of the most important communicative tools. It is always presented and accepted respectfully with both hands. However, Mary put their cards away much too quickly. In Japan, people use business cards as a conversation starter. You chat about each other's cards and work and do not put theirs away until they gently and respectfully place yours in safe keeping. Putting it carelessly into her jeans pocket was the ultimate disrespect.

Then, the fourth horror of horrors was that Mary should not have opened the gift in front of her clients. In a land where saving face is critical, it would be embarrassing to discover the gift they gave was not as nice as the one they received. What is worse, Mary hadn't even given them a gift!
