Have you ever heard of a 'Coffee with Postcard Café'? There is one in Leiden, The Netherlands, and the cafe is called Francobolli.
That is Italian for stamp ;)
At Francobolli's you can enjoy a cup of coffee or tea (with a sandwich, muffin or piece of cake). From several racks in the cafe you can choose from a selection of postcards. Nice postcards! Not the usual stuff that is for sale in the kiosks on the railway stations. When paying for your coffee, you also pay for the postcard, of course. Stamps are available at the counter as well.
Behind the counter there is a big calender. Every day has it's own slot. You can write your postcard(s) and ask the staff to put it in a certain slot. They will post it for you on that particular day. How nice is that? Super service!
