did you actually go inside to the shop area, or knock on any of the doors of the portacabins?Don't want too put you off mate but a few weeks ago i rang in the mourning to ask to fill a bottle up and the guy said no problem as they would be open till about 4:30 and then i turned up about 10 and no one was there or answering phone and hanged around for a couple of hours and no change so went home! hopefully it not normally like that
