It's all about perception. I had a friend who used to run a restaurant in NYC. They used to get complaints every once in a while about the serving size for their wine by the glass.

The solution? Smaller glasses of course. Complaints dropped to zero.

Most wine glasses are supposed to be only half full. The shape of the glass is designed to enhance the scent and flavor of the wine. Filling it all the way to the top ruins the effect.

Adding white mocha and peppermint to your coffee ruins the effect too, but that doesn't mean it isn't profitable.

Sadly, wanting good things leads to a lot of stress, at least in the US. (Go to Target sometime. Is there anything there that you couldn't get a higher-quality version of on Amazon for less money? Nope.)

That seems incredibly counterintuitive though, and can't see the mechanism that explains it. In the locksmith's case, the mechanism is that clients believe the duration of the task is directly related to the effort, and they are willing to reward greater effort.

The mechanism is that human brains are really, really bad at judging volume. A small glass full to the brim looks like it has more than a large glass that's half full. Bars often use a related trick, which is tall thin shot glasses - they look like they have more, even if they have less, compared to wider glasses.

Or big-looking shot glasses that have thick walls and bottoms. the glass looks bigger, and it's full... must be more in it.

To the magical thinker, a small glass filled up has "more" wine in it than a large glass half-full.

This is why we should be eating off small plates at home and buying the small donuts instead of the regular sized one. You get more satisfaction for the same sized meal or equivalent satisfaction for a smaller one.

I admit to using smaller forks and smaller plates when I'm grabbing a quick meal for in front of the PC - makes the food look larger, and it's easier to handle, too.

Beyond just the magical thinker, I'd assume the restaurant didn't use both size glasses at the same time so no easily-available means for comparison existed.

Expectations? If you put a big cup in front of me, I can expect you to fill half of it, fill it completely or anything in-between. If the glass is small, I expect you to fill it to the top, no uncertainty.
