TaKe on the scolding coffee cup

I walked into a coffer shop n Chelsea yesterday and order a large black coffee because I like my coffee to taste like coffee. The issue is that all these place serve their coffee scolding hot. It would be one thing if a deli did this but this place literally only sells coffee and they can't figure out how to serve it at a drinkable temperature

I walk over to the little table and thought to myself, what they need to offer instead of cream or milk is some iced coffee to dilute the hot burning coffee with something at room temperature or colder so that we can down the 500 degree coffee without making it taste like dessert
