Begging the canteen to refuse to accept cash slogan!

cash is precious, so it's better to pay by credit card. Do you still use cash to cook meals now? You are OUT! ! ! Credit card consumption, do you HOLD it? No cash, thank you for your cooperation. This canteen provides a fashionable, convenient, simple and fast payment method-meal card payment. If you have pocket money that is not urgent for the time being, please deposit it in the meal card. Thank you. Almost enough, right? If you think it's worthwhile, just adopt it. Thank you! ! If you don't feel solemn, forget it, when I volunteer to provide brain cells.
