It’s a safety thing too. Most girls want a public place for a first date. Especially from an app. A park is romantic and nice but offers little in safety depending on the size, location and popularity of the area. So, grab a coffee first. Then suggest a walk around if you want to get a little closer. No need to stay at the coffee house but a park for a first meet can sounds like a frightening proposal for a single woman.
