F&B Credit

Is it typical to receive F&B credit for each night stayed IF you don't use the credit in the restaurant?

I am currently at a Hilton Garden Inn in the Dallas-Fort Worth area and was told I had to use the credits each day in either the restaurant or the pantry otherwise I lost that dollar value. I could have sworn that if you didn't use the credit it was applied to your bill as a credit.

Is this accurate or is this something that Hilton has recently changed?
