When you are kicked out of an establishment, more often than not they will first ask you to leave and give you an explanation. It’s in their best interest to handle the situation as calmly as possible so you don’t cause a scene and make them lose business. You have leeway to contest the decision. Even if you’re banned, it doesn’t affect your life much.
Getting kicked out of your Google account can mean losing access to all your other online accounts. That’s disruptive to your life and you might waste weeks or months dealing with a situation where you have no recourse because you can’t reason with a human.
It’s routine that people get their Google accounts banned without understanding why, and thus can’t fix it. When you’re kicked out of a physical location, you’ll know why.
