Dominos stealing money

Why is it that when I take a cash order I owe the store money from the whole total and tip, but when it’s credit card it doesn’t do the same? Ex: I owed $162 but I took a $35.35 order with a $7.07 tip. I checked the system and it now says I only owe $152. But if it was a cash order that price and tip then I would owe $204.42. I kinda feel like that’s stealing and unfair. Am I wrong?
