Опрос от журнала "8 часов": "Чем Вы питаетесь на работе?"
Комплексный обед в фирменной столовой
Бизнес-ланч в соседнем кафе
Перекусываю в фаст-фуде
Покупаю что-нибудь в магазине по дороге на работу
Приношу вчерашний ужин из дома
Питаюсь бутербродами и прочей сухомяткой
Практически не обедаю, разве что чай попью
