Actually, everyone is in a hurry to have breakfast. Buffet can save time and manpower.
My shop will simply prepare eggs, steamed bread, fried dough sticks, soybean milk and all kinds of porridge in the morning.
When customers come, they just need to buy a coupon, take whatever they want, and of course, they can also buy it on demand.
In this way, most customers can help themselves, which is quick and convenient, and a few people can cope with a simple breakfast.
