I am not vehemently opposed to adding a squeeze of lemon to your diet soda. As a matter of fact, I feel like it sharpens the flavor a bit. However, I am a radical opponent of actually floating the lemon wedge in the drink. First of all I feel like it gets in the way of the straw. More importantly I have no idea who cut the lemon. I don't know if the lemon chef is a compulsive lemon washer who ensures that all the chemicals and accumulated grime from the citrus voyage were cleaned off before the lemon was dipped in my beverage. I don't know if the the restaurant employee that was assigned to chop lemons used soap the last time he performed ANY bodily function. I don't know if any one of the service providers made sure to avoid spraying spittle over the lemons while discussing their latest woes.
With those thoughts in mind I implore you, please do not dip the nasty lemon into my drink.
