Your $12 beer is about to cost $14: Madison Square Garden just signed a deal to make everything inside the arena 30% pricier starting next month, citing "inflation adjustments," while your paycheck stays flat. You'll pay $18 for a hot dog you could buy outside for $2, and don't even think about parking—they're charging an extra $10 to "offset delivery fees." Consumer advocates are calling it a "tax on fun," warning that the average family of four will spend over $500 for one night out before the main event even starts.
