When in a mini-panic room, it's not just about hiding from the apocalypse, it's about being classy while doing it.
Don't burp, don't fart, don't make eye contact with the other survivors.
Use a napkin, not your sleeve, to wipe your mouth. And for the love of all that is good, wash your hands before eating.
And remember, no one likes a dirty plate. Wash those dishes, survivors!
No shouting, no crying, no screaming. Use your inside voice, even when faced with the very real possibility of doom.
Avoid the 'I just rolled out of bed and put on whatever was nearest' look. Take a few minutes to iron your clothes, survivors. You never know who you'll be meeting in the bunker.
