What slogan should I use to close the store?

I hope I can help you. My first thought is: Please close the door of your quality. Or please close the door of your quality. There is also a quality person who will close the door behind him. After that, put a smiling face on it. They were embarrassed not to close the door behind them. Anyway, I have done it in similar situations in my previous company, and it is still useful. Remember to put a funny icon on it, preferably related to this sentence. If it doesn't work, it will be a lovely picture.
