The factors that make for a positive experience at MLB stadiums are obviously quite subjective—which means teams are never going to please everybody, especially not when dealing with crowds in the tens of thousands. Talk to a few stadium staffers—or take a quick tour of any Internet comment board—and you'll quickly learn that high prices rank as the most common customer complaint. (No surprise there.) And yet sticker shock is hardly sports fans' only stadium-related grievance. There is nothing safe when it comes to ticketholders' grumbling—from inclement weather to transportation delays to weirdly unfortunate customer interactions, like the time a Citi Field hotdog vendor warned a guy that the mustard packets can be tough to open and that he might need to use his teeth. "Well, the guy had no teeth," a concessions employee, who frequently interfaces with angry patrons, told me recently. "He was very upset."

So as another MLB regular season wraps up, we thought it might be useful to compile a guide to major league ballparks, detailing where fans are most likely to suffer one-star treatment. So, based on a highly scientific investigation—i.e. randomly selected (but 100% real) Yelp reviews, plucked from the Internet's comment bin—we present the absolute worst stadiums in baseball. These are the venues in which, for a premium price, you can endure verbal abuse, swarms of cockroaches, and very rude staff members named Britney. (Your reign of ill manners is at an end, Britney!)

Attend at your own risk.

"I am tired of political correctness..had to walk exactly halfway around the stadium for the ONE smoking area..sorry Nats, but you have lost a full paying patron..I won't be back." — Randall H.
