In companies I worked for, people never left like that. They would be talked to and then continued going to work although significantly less motivated. The firing on spot must have big reason like not showing up or drinking.

American companies do that thing where they fire you, you have to leave instantly and then they pay you salary for the time you would be still going to work in any normal company.

The rest of team spends time guessing the situation, trying to contact you to figure out what happened and generally is disturbed.
