Malaysia is fun for this. Just asking for tea (teh) will get you a hot sweet milk tea, if you want no milk you ask for “teh-O”. If you want no milk AND no sugar you ask for a " teh-O kosong", kosong basically meaning empty. Then of course there are the ice variants like “teh-O ais kosong”. So basically the default is getting everything except ice, then you add modifiers to take things out.
But tea language strangeness aside, Malaysian teh-tarik (pulled tea) is amazing and should get more global attention. Even the preparation can be quite a show and there are local competitions.
