they had a couple of tables in Glasgow train station on Friday when I was in and about 3 dozen people running about with clipboards intercepting passengers getting off the trains or waiting to get onto them, directing them to the boo ts in the station, all I was thinking was if somebody arrives off the train the general idea is to get out of the station and onwards to where they are going asap speedy......and if waiting to get on a train to sit for 10 hours to London, would they really want sticking with a needle first?....
