Steve gives some families time to come up with an answer or time to change their answer when the family is trying to steal. Yet other families he gets an answer right away.
Look at the season 17, episode 118.
The Nelsons vs Hopkins.
Time after time it seems that Steve gives some families more time.
Seems to me that he appears bias to certain families.
Also, Also he appears to frequently check out the women's behinds.
