For my group of 20th level characters who had a policy of carry everything you own, leave nothing behind, it went something like this when ransacking a powerful and old lich wizard's main lair who was known to be especially sinister....
<DM> You arrive at what you think is the door to the lich's laboratory. You see a green glowing rune like carving. There is another smaller door on the left wall.
<Fighter> I want to kick it in...
<Group> whoa...let the Rogue earn his keep...
<Rogue> I want to examine it to see if it's a trap.
<roll fails but not enough to set off the trap>
<Rouge> I don't think it's trapped but I'm going try and pick the other door first and see what our options are in that room, there may be an easier way in.
<No objections and he goes over>
<Fighter> I kick in the main door.
<Crazy looks from group>
<DM> you want to kick it in the door with the glowing runes?
<Figter> yep. I kick it in....
<Group freaks out>
<DM> OK everyone within 10 feet has to roll for all of their magic items againist Mordy's Disjunction. (this was everyone but the rogue)
They basically lost everything, the Ranger managed to save his +1 arrows.
It's a good thing I have a rule about player vs player
