A most welcome method.These days almost all people are completely getting addicted to their smartphones and even while eating also they are not able to keep the phones away. They are getting wedded to these phones. Even when they go to restaurants also instead of concentrating on the food or talking with the people with whom they came there, they are spending their time on phones.
Some Restaurants in Japan are not happy with the customers because they are eating like a machine but not enjoying the food. So many Resturants started collecting the phones and giving back when they are leaving the hotel. Many restaurants are displaying hoarding asking the customers to switch off their phones. In some hotels, they are offering 10% discount on their bills if they are not talking on the phone till they finish their eating and pay the bill. Some hotels are collecting the phones of a group of people who are coming for eating in groups and if anybody is going to the phones in hurry and seeing the phones for missed calls are punished by asking them to pay the bills of their friends also. I think it is a welcome method and do you feel in India also this system is good?
