1. There is assigned seating
  2. You have a microphone
  3. It is scheduled to last two days
  4. There are 40 people at the table
  5. People are looking at their phones
  6. Awkward silence after a bad idea is shared
  7. You are talking and no one is listening. Or, someone else is talking and you are not listening.
    Either way, both are bad.

  8. People complain about the catered snacks
    It would be one thing if they were complaining about a full blown meal, but in this case they were complaining about the flavor varieties of the snacks!
