Nothing bugs me more than going out to a restaurant and seeing the list of prices for alcoholic beverages. They’re always so much more—like double or even triple the price—than what you’d find if you just bought the drink yourself.

A bottle of wine that usually goes for $8 in your local liquor store could cost something like $30. In fact, a glass of wine in a restaurant is usually marked up by 300 percent!

“In general, if someone is running an effective by-the-glass wine program, the menu price of one glass is the wholesale price of the bottle,” says Steven Morgan, wine director and manager of new West Randolph Street restaurant Formento’s.

And what about beer? Craft beer is one of the best money-makers for restaurants, and can sometimes be marked up by a whopping 600 percent. Depending where you go, your favorite beer might cost as much in a restaurant than if you just bought a six-pack in a store.

Then there’s bottled craft beer, with a markup of about 350 percent. “Opening up a $5 bottle of beer or a $50 750ml bottle of something rare doesn’t cost me any more money,” Roper says. “The labor is exactly the same.”

Nevertheless, going out to eat is about the experience, and we buy the booze, despite the price. We already know we’re getting ripped off, so it is what it is.

The next question is what size drink should you order? Obviously the one containing more is more expensive, but it might be worth it since you’re getting more. Right?

We’d hope. But one man decided to challenge this notion. He recently went to Applebee’s and ordered both a large and small beer to see how much more beer he’d be getting in his large glass.

What he found was pretty alarming. It turns out Applebee’s served him the exact same amount of beer in his large glass as they did in the small glass!

This is not the first time something like this has happened—it seems to be a weirdly common phenomenon. Back in 2014, four people sued an Idaho arena because they got served a $7 beer and a $4 beer, and both had the same amount of liquid in it.

“While different shapes, both cup sizes hold substantially the same amount of liquid and are not large versus small in actual capacity,” attorney Wyatt Johnson wrote in the lawsuit. “Defendants knowingly sold each of their beers in a similar manner at each event held at the arena where beer was sold for at least the last five years.”

We can’t believe places get away with something like this! If we’re ordering the large beer, just give us the large beer, dang it!

Like we said, if you’re trying to get the most bang for your buck, just stick to a glass of wine. Even though a glass of wine usually costs more than a glass of beer, the markup is less (though still sky high).

What do you think of restaurants serving the same amount of alcoholic in a small and large glass for different prices?
