well i hope this the is right place for the tread.....

but about a month ago I walked into my local computer store just to see the prices of some network gear.Im planning a wi/fi network for home and my studio.So I'm walking around when I see a cool computer runnung XP. so I press the enter key to see what happens and I get the log in screen.It has two users
"Administrator" and "sales".so I decided to throw some passwords at it and long behold I got into the sales account...At that moment I saw a worker walking close so i just walked out the store.I did not see much but ...I went back to the store and found out that there is a phone line hook to it.My question is what would you do if you were me? tell them, dont say a thing.
have some fun or whay?

Thanks for you info and comments.
