fire prevention and theft prevention are inseparable from the word "care". First of all, we should formulate sound rules and regulations at the cashier's desk, stick them in a conspicuous position where the cashier can see them, have monitoring probes, reward those who observe the regulations well, and punish those who violate the rules (deduct wages), so that employees can be motivated and persistent to be alert ideologically. Then pay attention to the details in the practice process. For example, the cashier should put an end to storing any inflammable and explosive goods, such as lighters, pesticides, hairspray and mousse. Cashiers can't spray gel, and their hair should be tied up. To post: gas leak, no smoking. Such signs frighten guests not to smoke with fire.
