We've got a problem ... it looks like we'll need more spotlights on the exhibition booth . The client thinks it's too dark , and they want to add halogen lighting . We've already got 3 sets of track lighting from you guys , do you think you could help us out and throw in some halogens ?   Oh ... Um ... I don't think so . you know the halogen lighting is much more expensive than your track lighting system . Plus I'm going to have to call in some guys to install it for you . That's not going to come cheap .   But it would only be adding to the existing structure . We're not talking about anything new here ...   It doesn't matter because we will still have to call the electrician out , and they are union labor . It'll cost you a pretty penny ...   How much do you think it would cost ?   Mumm , I estimate it'll run in the neighborhood of ... $ 500 per light .   $ 500per light ? ! That's ridiculous ! It can't possibly be that expansive !   It is , I'll tell you why . We'll have to call in the electrician , he's going to charge overtime now because it's already 5PM , and it will probably take him an hour a light . Plus , the halogen lights take more electricity , so your electrical cost is going to be higher as well .
