Has anyone here used a self service machine in a post office?

A couple of years ago I went in to the newly refurbished post office in the town centre to post a letter to The Netherlands, and was introduced to the new self service machines by a member of staff. I had my letter dealt with by the machine, and the process did look awfully complicated. Fortunately, the lady in the post office did it all for me .

I went in the other day to buy some stamps, and there was a queue, so the lady suggested I get my stamps from the machine. She did the whole process for me.

Self service is always fun when there is someone to do it for you .
