i phoned through an order for some metal to a local dealer. After a few days they phoned back to say it was in so of I toddled to the industrial estate to pick it up. I just could not find the place. I then phoned them up to ask how to find them, to which I got the answer " opposite ZZZZ there are three units, the first is YYYY we are the middle one next to them." So we find ZZZZ and sure enough opposite them is YYYY, the next big box is some one else, err no, round the block again. I then went down YYYY's entrance and there were another two shuttered entrances, both with a reception door. So I went into the first door into a foyer and rang the bell, while I was waiting I read the notices on the notice board and found out that I had come to correct place.
Point to be learn't I guess its because of thievery that these places might like to keep a low profile, so phone up to get the exact location (my sat nav. was no use). I had asked some locals where they were and even they did not know.
