The first thing that needs to be done is you should pass the basket of bread to the client first. This will show good manners and you know that you have to please your client especially if you want the deal to push through.
After the client gets bread, that is the only time when you can also get bread. It will be rude to get a piece of bed and place it on the client’s plate because you do not even know if the client wants to have bread or not.
If you take a piece of bread before offering it to the client, this sends a message that you are putting your needs first. Ignoring the bread basket is your own prerogative but at least offer it to the client first before you ignore it.
