I was chatting with a HelloTalk friend who’s a barista. I told him that I love coffee. A minute later, he replied, “Frappe is ready. Gratis.” I learnt two words from him Barista A barista is a person who is professionally trained to prepare and serve coffee, especially espresso-based drinks, at a coffee shop or café. Gratis Gratis is a word that means "free of charge" or "without cost." It originates from Latin and is commonly used in several languages, including English, Spanish, and Italian. In this context, it implies that the frappe is being offered as a gift or without payment.
