Bleacher seats vs. box seats at sporting events: Is there discrimination going on?

Baseball season has begun and the talk has begun as well about the drinking at stadiums across the country.  Not only is the discussion on excessive drinking, but it is also focused on the types of drinks being sold dependent upon where you sit.

At Fenway, the bleacher seats are $28.  Here they sell beer. In the better seats, like the box seats, top shelf liquor is offered, like Absolute vodka, along with beer and other beverages.

The "bleacher people" feel they should be offered the top shelf drinks as well.  They feel they are being "discriminated" against and one is assuming they cannot afford the top shelf liquor since they are in the bleacher seats.

Is it a case of discrimination or simply wishing to make the higher priced ticket buyers feel they are receiving a "bang for their buck" by allowing for perks like top shelf liquor?

And more importantly, the conversation should be focused on the amount of liquor being overly consumed by the attendees at the sporting events.  Personnel are being criticized for not "shutting guests off when they have had one too many".  Stadium personnel are not acting like licensed bartenders and watching the purchaser closely prior to allowing the purchase of an alcoholic beverage.

So, I suggest having "drink coupons" attached to each ticket to the sporting event.  Perhaps 3 drink coupons per individual.  Yes, this will lead to some abusing the system and selling their drink coupons within the stadium.  BUT, I think it will help with the excessive drinking problem.  And some help is better than doing nothing.  And, yes, the owners of the stadiums will be reluctant to curb the drinking, since, after all, they are making $$$.  But at what cost?  Drinking and driving do NOT mix and we all should do what we can to avoid a potentially tragic result of the excessive drinking.

What are your thoughts?
