Little Caesars arena pure ripoff

Went to see trans siberian Orchestra last night at the little Caesars arena in Detroit. You want to talk about an absolute ripoff? A 32 Oz cub of soda that cost them less than 50 cents to make was $9.67. No refills. If you have no issue with this, more power to you, but I'm not going back there when they charge massively excessive prices for a simple drink. That's beyond ridiculous.
