Unless you ask for unsweetened tea here in Indonesia you will eventually get either diabetes or rotten teeth. It's more like 'Do you want tea with your sugar?'
Tini drinks bland tea should be correct as well?
In context, 'tawar' means unsweetened, but American English is as likely to use "plain tea" for 'teh tawar'.
Either i have hearing problems or the guy speaker doesn't talk loud enough
