Walking past the subway turnstiles, a pal asked did you see that mother and child standing either side of the barriers?
In New York for 89 bucks a month you get unlimited rides. Actually they are limited in one way, you have to wait 18 minutes between swiping your card through the turnstiles. I've been caught out by this a few times.
In any case the mother and daughter were waiting 18 minutes until they could go on their way together.
