If you dream snooty butlers carrying trays of things, it means you will become successful and rich enough to afford your own butler.
If you are working as a butler or waiter/ waitress, hen this dream has no special significance for you. Since your job is of that theme, you also dream of the same theme, as your dream is a continuation of your day’s theme.
The dream interpretation of the symbol of butler can mean you have an assistant, or intermediary, who helps you. If you are experiencing difficulties in your waking life, or you’re very busy, then this dream is a hint to you, to get an assistant.
