Have you ever gone into a store expecting something and finding it wasn't what you thought it was, but the sales person was so delighted to see you, and you suspect you may be their first customer of the day, you feel you should buy something and look for the cheapest thing there is?
I thought I was going into a bakery when I got inside realised it was a speciality cake shop. The sales girl was so thrilled to see a customer I thought I cannot walk out again empty-handed so spent just over $20 on the cheapest cake I could find which turned out to be a flavourless very tiny baked cheesecake.
