Close After Opening

Having oden (a Japanese dish consisting of several ingredients cooked in a shoyu-based liquid) for dinner with a friend, I stopped in at a convenience store and found this sign at the door.

In the store that has a lot of drinking places nearby, we also spotted signs aimed at drunken people, telling them not to lie down on the floor (interestingly the message was written in hiragana, the simplest form of Japanese, so that even people with a dim consciousness could barely see).
