True or False: Lemonades come with a lemon garnish.

The statement that lemonades come with a lemon garnish is considered false because it is not a strict requirement for every lemonade. While many establishments may offer lemon garnish as a common presentation element, it is not universally applied. The garnish can vary based on the recipe, the establishment's standard serving style, or the preferences of the customer, meaning that not all lemonades necessarily include a lemon garnish.

When considering the other options, the notion that lemon garnishes are only provided if requested or during certain seasons does not capture the general practice, since serving methods can differ widely from place to place regardless of season or specific requests. Therefore, the classification of the statement as false accurately reflects the variability in how lemonades are served.
