Is there a global citrus surplus? There has to be a reason every restaurant insists on putting lime in your soda and lemon in your water. At some establishments, you have to ask for the citrus not to be inserted in your beverage.
When exactly did asking for water mean you were also requesting fruit? This seems like a technique designed to get rid of unwanted items, such as, apparently, lemons and limes. You know what they say, if life gives you lemons, open a restaurant and give them to someone else.
With so much citrus available, why is anybody bothering with vitamin C pills? Has scurvy been eradicated? How long before they start adding unwanted citrus to food as well? Oranges in the spaghetti? That wasn't a meatball after all!
