Is going Dutch a problem?

Some people believe that going Dutch on a date is never a good idea.  If one of you asked the other out, should one person always pay for the date?  My friend Blair was met up with a guy for a Brunch date.  She was offended when her date asked for her part of the bill.  She automatically thought that he didn’t like her since he wasn’t paying for her food.  He said she suggested they go to Brunch and picked the location, he didn’t expect to have to pay for her.

Would you get offended if someone expected you to pay your own way on a date?  Do you think  going Dutch is ever appropriate in dating?  Do you think it is something you have to decide before her actual date?
