My comment about eating before or after raid can be found below.
Such as if raid starts at 8PM and ends at 12AM, do you really want to eat dinner every raid night at midnight?
Then they need to go to bed ASAP to wake up in time for work in the morning. That's just not healthy for your digestive tract!
Even a 15 minute break at 10PM for "dinner" is barely tolerable especially if you want to eat well/properly. Then there are dishes to be washed, trash to be taken out...
