Sure we can all take a moment to fleece a store of the goods [how many threads on here pertain to "theft" as a means of improving the character through then selling the purloined goods back to the shop owners themselves, lol try that in Morrowind]
that's very bad roleplaying =)
i used to do that back in BG1 when i didn't care about roleplaying but for the most part, i have tried to actually roleplay my character.
of course right now i am a thief so it's perfectly acceptable to steal from people =)
