Sphinx Patterson, 35, said numerous staff were drinking beer in the canteen on the seventh floor of the Canary Wharf skyscraper. He said: "People are walking around in shock. Girls are crying, blokes hugging each other. People don't know what to do." Mr Patterson, from Willesden, who was told his classes had been cancelled, added: "It's not just the high-fliers who are losing their jobs. I spoke to a receptionist and she was packing up her pens."
