The interaction that messes me up all the time is the side button and payment related stuff

One press turns on/off the display Two taps enables Apple Pay

Quite often my timing is not perfect or one press isn’t hard enough so I shut off the display

Then, paying with Apple Pay is a double press but paying for transit is no press. but often I’m absent minded and as I’m walking through the transit gate my brain thinks “must pay” “pay = double press” so I subconsciously double press and the gate screams since is not in transit mode now it’s in Apple Pay mode
