I read of a case fairly recently, where a man was in the same situations as your cousin , ummmm. He wrote a very eloquent letter to the service station saying something along the lines of "if a person can't pull into a service station to rest when he's feeling tired in order to avoid a possible accident, then I question your right to a licence for advertising yourself as such, and I will write to the appropriate authorities to look into whether you should have such a license." He wrote it much more eloquently than me, of course. He received a letter soon after saying the case was dropped. Your cousin should try that.
