Rogue PCs in many of my own campaigns, and in campaigns where I was a player, have announced that the are performing "Standard Thief S***". I generally take this to mean...
... they are ahead of the party by at least 30 ft.
... they are attempting to move silently.
... they are searching for traps.
... when encountering a door, they do a search for traps on the floor in front of a door and then search the door for traps.
... they listen at doors.
... they attempt to unlock locked doors.
I occasionally find this irritating -- not the procedure, but the fact that the player feels they can summarize all of this as standard operating procedure and hand it off to the DM and not worry about it.
On the other hand ... I have played rogues before ... I know the tedium of repeating all of that stuff. It only makes sense. Unless speed is an issue, if I'm scouting ahead I'd do all that stuff all the time. If I don't establish a SOP, then it becomes a game of "can the DM catch me forgetting one of my standard steps".
Finally, does a procedure like this essentially nullify the fun of traps in a dungeon? Frankly, unless I'm running published adventures, traps are the least likely thing PCs will encounter. Maybe it's because I don't find them fun, and maybe it's because any reasonably cautious rogue is going to find them?
Thoughs?
