This business is not doing well ah, and the boss to chat this depends on what kind of business. If it is to do side food stores, he generally have their own channels, and the price point you can no longer have too much discount to him. If it's a new business, start with a barbecue stand. But they that quantity is not fixed. There are more and less. And may also want you to lay goods to him. If you are chatting with the owner of the restaurant, you should choose the right time, not too early, about 3-4 o'clock. Because that's when he might have time. If it is to get breakfast, you do not want to touch the nail. If you want to find also to find to do night snacks. Just pay attention to one thing when you talk to them. Don't be long-winded. The first thing you need to do is to get a good deal of money. Please adopt
