I run the Pivotal office in Singapore. Breakfast is wonderful, but it's hardly mandatory.

Standup at 9:06 is important, though. In order for pairing to work, you need to have everybody there at the same time.

The iron bargain is that you work a rigid eight hour schedule, but then you go home (or wherever) and don't think about work. No overtime or crunch mode, ever.

It's not for everybody, but many folks really really really like it.
