Carelessly handling a business card

Beckoning someone by curling your index finger towards yourself

Not following the instruction of the eldest person in a meeting

Not taking a business card seriously

Keeping your shoes on when entering a home

Showing the soles of your feet

Sitting cross-legged in a chair

Altering your meal (eg. condiments)

Eating anywhere that does not serve food

Filling your own glass

Not slurping

Sticking your chopsticks straight up in your food bowl

Using your own chopsticks in a shared dish

Telling people to help themselves

Blowing your nose

Laughing with mouth open

Not declining gifts

Not wearing a protective mask while sick

One handed gift giving

Talking loudly on the train

Talking on your cell phone on train

Tipping
