AXESMI - relocate the lunchroom to the local Hooters. All kindsa health in there....Alice would be in kill mode if she found out about it....PHB would be blamed as all executive decisions belong to management....
We had a 'Team Leader' who called a lunchtime meeting but every time she tried to start business we would start passing food or drink around, open chips bags loudly or disrupt in any polite way possible. She took the hint and never tried it again.
This was the federal government so we probably had a little more leeway at ignoring her than PI guys might.
I'm thinking this is one of those brown-bag "lunch meetings", a sleazy way to take away the lunch break from salaried people. So Wally is exploiting an opening where PHB knows he's on ethical low ground. Good time for Wally to continue his couch research.
