IMADA CS Lunch AlgorithmSuspended - we now eat in the coffee room all the time.
Traditionally, we deviate from this algorithm when we have guests (speakers or external examiners) that many of us know or are interested in talking to, and eat when it fits the guest's schedule. In those cases, I'll send one e-mail informing you that the algorithm has been suspended that day, and another one when it's time to go.
The implementation of "we had morning bread" is only semi-automatic. Thus, I have to do something (other than just eat bread) to actively postpone lunch. I suggest that if I forget, we just do whatever the e-mail says.
