GOLDMAN Sachs boss Lloyd Blankfein has warned his employees to avoid high-profile spending, as The Post reported -- but his wife evidently didn't get the memo.

Laura Blankfein and her friend Susan Friedman, wife of another Goldman honcho, Richard Friedman, caused a huge scene at Super Saturday in the Hamptons last weekend when they arrived at the event before the noon start time and balked at waiting in line with the other ticket-holders.

"Their behavior was obnoxious. They were screaming," said one witness. Blankfein said she wouldn't wait with "people who spend less money than me."
