What's the downside with being a utilitarian?

I was talking to a professor the other day about why philosophy should be gen ed in high schools, and one of the things I said was "I don't think anyone's worse off after learning about utilitarianism".

He then responded by saying something about how I should meet his utilitarian friends who take it to the extreme and aren't doing very well. 

I was just wondering what he meant by that, what's worse than can happen with utilitarianism?

What he might be thinking of is that utilitarianism is a very "demanding" ethical framework.

For example, many argue that donating all (or almost all) of their money would surely increase utility; african children who starve could be saved by what just might be a fun movie at the cinema or a nice dinner with his friends. However, an ethical framework that calls for hard work and then donating all the hardly earned resources away is one that demands much, maybe too much from whoever follows it.

That said, not all agree that this is what you should do to maximize utility.
