Those prices look no different than, say, regular Dodgers game prices.
Yeah. I worked a game for my sons wresting team at 49ers stadium this year, and sold Bud and Bud Wipe for $10.75/bottle. Did hundreds and hundreds of transactions, doing the math purely in our heads (there were four of us). At the end of the day, we counted the empty cases, wrote off whatever was added incorrectly as 'breakage,' and dumped the envelope with however-many-grand into a chute and went home. Crazy-weak inventory control, but at that margin, they didn't care.
What kills me about that pic, though, is the $15 souvenir popcorn. Lol.
