Went to the game last night and was charged $70 for two Art Cars in the Astros cups. Did it really go up that much or was I overcharged?

Edit: I looked at my statement today and I'm an idiot. It was $41 with tip. I must have drunkenly saw $35 twice on the card reader and thought it came to $70. The happy hour before the game got me🤣 I'll continue taking my lashings from you guys. I appreciate it. Great game last night!
