"I went to a sporting goods store and they asked me for my phone number when I was paying. I was in a bad mood and didn’t want to fight with the clerk so I told them our local area code + 555-1212 (which is the old number for directory assistance), clerk accepted it and I left.
When I checked my receipt I had a huge number of loyalty points – because apparently, a ton of other people did the same thing. I called the office the next day and switched the “account” to my new address. A half-dozen times over the next few years, I went and got free stuff with all the points that I kept racking up as one of their most loyal customers."
