On the Stena Harwich - Hook of Holland day crossing yesterday, Ship arrives and passengers go the the vehicles. So I am sitting in the van on the ship waiting to go and along come two police officers with a breathalyser kit. They get the guy in the lane next to me to do the routine and take his details, they let him go so I guess he was ok but they seemed to be doing spot checks as they moved on to another vehicle farther back. Some caution needed if you plan on drinks on the Ferry? I have wondered how many people are over the limit when they get off Ferries when I see the rate of drinking that goes on.
