Like I say, I wouldn’t make a comic if it wasn’t true. This woman gave the turnstile the look you usually give when you’re not sure if your swipe worked, but it was when she was exiting the turnstile. Maybe if this were Japan or one of those other countries where you need to insert a ticket or pass on the way out, but even with those turnstiles if you’ve made it to the other side there’s nothing to check.
