COSTA "Window in"

I am a passionate about coffee and sales. Therefore I came up with the idea for COSTA coffee shops. Why COSTA, well it is in my neighborhood, however it may work for any other brand.

The story As a young parent I made kilometers while walking around with my son in his early months. After long battles of making him fall asleep I was making very long walks (2-3 hours), unprepared, in cold and warm weather - various conditions. The main dream was to have a coffee - to waken up, get warm or cold (ice coffee!). However, entering the coffee shops equals waking up of a kid. Mainly because of change in temperature, noise and smell. All the things that in normal conditions make those places so magical. However not when you are doing all your best to keep the baby asleep as long as possible.

Solution "Window in" where I could knock and make and collect an order. I understand that the buildings do not allow such solutions (architecture style, building infrastructure and other obstacles), but the staff in most coffee shops is kind, and after a knock, smile and wave of hand they could react and step out to collect/deliver an order. This would be a game changer for many young parents, who are somehow "disabled" in operation of ordering a coffee while being on a walk with a kid. Also, what a great story to share in PR-marketing-CSR campaign? :)
