As a child (last century..or was it 2 centuries ago?) I don't recall ever ordering tea as "sweet" or "unsweet". It came without sugar and you put in whatever you wanted from a round container with a little hole on top with a flap. Then came sugar packets for places who thought people were wasting sugar - really that wasn't common til the sugar shortage about 1974.....artificial "sweetener" came in a liquid in a bottle if available at all, then came the little pink packets about the same time. Slowly over the years that has given way to the sweet/unsweet tea mix. UP until about the mid-70s, the only place I ever recall being asked if I wanted "sweet" tea or not was in LA and E. Texas and that was hardly universal. So when did the nation embrace the notion that tea came in two flavors - sweet and unsweet? And are there any restaurants in the nation where they don't ask you if you want sweet or unsweet and still serve you unsweet and let you do your own doctoring? Guess I am old fashion. I get tired of saying "unsweet" and further, if I wanted a ^%$# lemon slice on top I would have ordered lemonade. And what's up with these outfits that bring it with a LIME slice?
