Isn't it TTF? The number of unlimited lanes sure looks like it has a negative correlation with the average customer age. The three stores with the oldest customers don't have any and the more unlimited lanes you have, the younger the average customer.

It is TFF. If you re-arrange the order of Self-Check Unlimited Lanes by Customer Age from youngest to oldest, you get the following:

CA - SCUL
28.40 - 6
29.90 - 8
32.00 - 4
34.50 - 4
34.60 - 6
38.73 - 3.56
38.80 - 0
42.50 - 4
50.50 - 0
56.70 - 0

As you see, there is an up-down-up-down-up-down pattern. If you eliminated the ages 29.90, 34.60, and 42.50 then there would be a negative correlation.
