However, in many jurisdictions doing so amounts to theft and is prosecuted from time to time - admittedly usually where the theft is repetitive or used to facilitate a second illegal act (e.g. downloading child porn).

A brief search will also return bulletin board discussions about unsecured connections being a source of risk from Trojans and key loggers etc camped equally unlawfully on the unsecured router.

It may be less contentious where you went to the bar/ cafe , bought a drink and obtained the password for later use but we all need to be aware of the risks we run.
