(Answer is applicable to the USA only): A warrantless arrest is never served. A warrantless arrest is performed. Following the warrantless arrest, the arresting individual (typically) or authority is required (usually) to provide the courts with a warrantless arrest affidavit wherein the person making the arrest articulates the probable cause for the arrest, which then is submitted to a judge for review. The arrested person will already be in jail or otherwise in custody (and possibly even bonded out), before the signed warrantless arrest affidavit becomes available to the arrested person.

Depends on the circumstances. yes
One major reason (or justification) is any immediate threat to public health or safety, such as where a person inside a locked, private room is screaming. The authorities can have the door opened, forcibly if necessary, to determine if there is a violent crime in progress, or a person at risk, and can seize any evidence of crime that is in "plain sight" when they so enter. Similarly, many police officers will ask for consent before searching a suspicious person or entering private property to investigate a report of a disturbance, thus making most such searches or resulting seizures legal and warrantless. However, there is a fine line of "consent" under duress, and the scope of such consent, both of which can be aired in a hearing on a motion to exclude any seized evidence.
The person is lonely.
