Carelessly handling a business card

Beckoning someone by curling your index finger toward yourself

Not presenting a business card after a meeting

Wearing casual clothes to business meeting

Keeping your shoes on when entering a home

Giving a firm handshake

Men displaying skin

Showing the soles of your feet

Sticking your chopsticks straight up in your food bowl

Not slurping

Telling people to help themselves

Tipping

Gifting knives

Having one hand in your pocket

Speaking with your hands in your pockets
