Ken Ozeki has strong opinions about the tipping culture in America — particularly compared to his native Japan.
  • In a recent survey, more than a third of US adults said "tipping has gotten out of control."
  • Californian Ken Ozeki,  born in Japan, said the Japanese don't feel obliged to tip like in the US.
  • He told Business Insider he often pays in cash and picks up food to avoid the charges.

Whenever Ken Ozeki buys a cup of coffee, he will tap the "custom tip" option on the swiveling tablet and round up the price to the nearest dollar.
