I'm a sign maker, it's all road signs talking like the ones you seeing being plastered around the city centre shortly, make the big mofo ones for motorway... Anyway I had been doing mainly signs in aluminium all day, get this one job has about 40 decent size signs to do. Get it all cut in aluminium, thinking Yea glad that's done, the next department come along ready to lay the facings on and ask where the job is, I'm like there. They then point out its meant to be cut in a different material and much cheaper material called GRP :-(
