Ordering a coffee (Advanced): The size of coffee you want.

🇨🇳 [你好] is standard and polite, but in many real coffee shops people often skip greetings and go straight to the order. Staff may say it to customers more than customers say it first.

💬 In [麻烦], [麻] and [烦] work together as one word meaning something like [excuse me] or [please]. On its own, [麻] usually keeps its basic meaning, not that polite service meaning.

💬 In [麻烦], [麻] and [烦] work together as one word meaning something like [excuse me] or [please]. On its own, [烦] usually means [annoying] or [bothersome], not the polite expression.

🇨🇳 In shops, [麻烦] can soften a request, a bit like [sorry, could you...]. It sounds polite without being stiff.

💬 [一] often changes sound before another word: before [个] it's read (yí), as in [一个]. You'll hear the same shift in many common phrases, not just numbers said alone.

💬 [杯] is a counting word for drinks in cups or glasses: [一杯咖啡], [两杯茶]. In size names like [中杯], it keeps that [cup] idea and means the medium cup size.
