Why would they have to?Only the original owner can do that, although if you take it to a carrier store they can do it, and at no charge.
Per Google :
If you're using a device with multiple users, each user has separate account settings so make sure you’re logged in as the correct user before removing any account information.
Open the*Settings*menu**on your device.Under "Accounts," touch the name of the account you want to remove.If you’re using a Google account, touch*Google*and then the account.*Important:*When you remove your Google Account, all the email, contacts, Calendar events, and other data associated with that account will no longer automatically sync with your device.*Touch the Menu icon**in the top right corner of the screen.Touch*Remove account. If this is the only Google account on the device, you may need to enter your device's pattern, PIN, or password as a security measure. This ensures that only you or someone you trust is removing the account from your device.

Hey!
I wanted to do the same, although the info I found on google is kind of outdated. Do you have any relevant info that I can easily remove my Gmail account from the device that has been Stolen last week.
I am much curious about my personal information on that phone.
