1. meal replacement coupons are used to consume the food specified in the store (for example, some stores offer couples' meals, children's meals and adult meals, and you have 2. Couples' meal can only be the food designated by couples' meal in his shop, so there is no choice. Choose less, no refund, choose more money)

Vouchers mean that you can consume any food in the store. You can use vouchers when you check out, instead of RMB with the face value of vouchers.

(generally, I don't want to renew any coupons. For example, your voucher is 100 yuan, but you can't find it after spending it in 90 yuan. But if you spend 150 yuan and use 100 yuan in gold rolls, you have to pay 50 yuan RMB. )
