McDonald's has suspended a trial providing Net access in its restaurants after customers complained that they couldn't stomach porn with their burgers.

Three outlets in Kilmarnock, Dunfermline and Paisley began a scheme to offer "McNetAccess" in the summer. Although McDonald's took measures to block access to adult sites, this failed to stop porno pop-up ads from appearing on screen.

In a statement McDonald's said: "As soon as we were alerted to the issue we suspended this trial service. We are currently investigating this matter and will be taking appropriate action before resuming service.

"The Internet provided a great service for our customers. Most people used it properly, unfortunately a small minority appear to have misused it." ®
