changing password to enter cb (in General)

ok i have to go in internet cafe to play cb while i am on vacation for the holiday because my family dont have internet at home.

while i was at this internet cafe i went to smoke a cigarette outside and when i came back some very old dude plug a usb key in the computer i was using so i am very scared he might have stolen the personal information i put it (like my e-mail and my password)

well i was very mad at him but he acted like he did not know what was happening !!
i am actually changing all my password on all sites i go and i was wondering if i can change the password i use to play cb because if this guy ever..hooo i dont want to think about this..
anyone ever change is password?
why did this guy plug a usb key in the computer i was using?
am i paranoid or is it a non-scary situation

what would you do if you were me?

hit settings, in the lower right hand corner is the place to change your password...

While it's not impossible that the man was trying to steal your information, it is unlikely.

what would you do if you were me?

Stop smoking and enjoy more hot dogs >:) ...and don't leave your computer unattended to at an E-Cafe, especially with elderly hackzors
