In light of the recent Build-A-Bear pay your age debacle, Chuck E. Cheese's is hosting a Pay Your Age for 30 minutes of free play today only. I called and verified that the Lubbock location (5612 W Loop 289) is participating today as well:

Didn’t get to Build A Bear? Come in on 7/13, pay your child’s age, and they will get 30 minutes of All You Can Play. Offer available Friday, 7/13 only in participating U.S. locations where Chuck E.’s Play Pass is available. (Maximum $9 for 30 minutes)
