The first meal I ate in Cienfuegos, Cuba, minced beef with rice, counting the 10% service charge, a total of 1355 Cuban pesos! The taste is ok, it's sweet! I have been to seven or eight countries, and I feel that their food and beverage charges generally have a 10% service charge, which is basically used to pay the waiters. It stands to reason that after collecting the service fee, you don't need to tip separately. But sometimes for the sake of face, Chinese often tip a little. It feels like this is face money, just to prove that Chinese does not lack this little money?
