Urgent! help with Chrome sync data?

[єиdℓeѕѕ mιdnιgнт]

I left my computer at the repair shop so they could fix it but I completely forgot to log out of Chrome and I don't want anyone to see my history or use any of my social accounts, such as twitter, facebook, gmail, youtube and many more, I have all my data and passwords saved in my chrome account so they could easily use them, is there any way I can manage that from the computer I'm currently using? like could I log out that computer from the one I have right now? I've read that if I change my google password they can't log in again is it true? what if I deleted my saved passwords and history? when they start using the computer again would they be gone?

Computer Techs are entirely too busy to rummage around in customers' personal stuff, even if they were inclined to (which is highly unlikely). I recommend you not worry about it.

It's a good idea anyway to never bring cars or computers to a repair shop you don't trust. That said, you will most most likely be just fine. I hope this at least puts your mind at rest.
