A cup for cold drinks should be soaked in ice water, and it should be taken out of the ice water when it is used, so as to avoid the disharmony between cold and hot and force the cup to break; 2, hot drinking a cup should be soaked in hot water, when using it, take it out of the hot water to avoid the disharmony between cold and hot forcing the cup to break; 3. In the process of delivering drinks, trays should be used for shelving, and waiters should wear gloves; 4. When the drinks are presented, coasters should be distributed at the same time or a corner of the dining table should be prepared in advance (standby); 5, hot drinks with spoons, in principle, not with straws, if customers need straws, they should be reminded to use them safely; 6. Cold drinks are equipped with straws (spoons can also be attached); 7. Take different measures to deal with the damage in different situations: for example, if the damage is caused by the waiter, the bonus should be discounted, which must be linked to the internal management reward and punishment regulations.
