I don't go to restaurants that much anymore. But when I do, I appreciate honesty from the server. The fact that he/she doesn't claim to love every menu item is both refreshing and resassuring. I tend to remember that server and would go back (assuming the food is good) in a second.
The same goes for people who "serve" music. If you listen to Kiss between 2pm and 7PM during the week, you probably have figured out that I'm not for sale when it comes to music.
I'm warning you that I'm not going to pander like every other "DJ" in Milwaukee and claim to love the new Taylor Swift song. Honesty is a rare commodity. I'm bringing it back; regardless of how unpopular it is.
