> the wine glass scenario is a _realistic_ scenario
It is unrealistic because if you go to a restaurant, you don't get served a glass like that. It is frowned upon (alcohol is a drug, after all) and impractical (wine stains are annoying) to fill a glass of wine as such.
A pelican riding a bike, on the other hand, is realistic in a scenario because of TV for children. Example from 1950's animation/comic involving a pelican [1].

A better reason why wine glasses are not filled like that is that wine glasses are designed to capture the aroma of the wine.
Since people look at a glass of wine and judge how much "value" they got based partly on how much wine it looks like, many bars and restaurants choose bad wine-glasses (for the purpose of enjoying wine) that are smalle and thus can be fulled more.
