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 .
