After making the clip - youtube.com/watch?v=7pETAF5X460 - it just happened that a person I tried to convince earlier that day to make a time-selfie, came into the petrol station on his scooter. He seemed intrigued by the internet popup box, and went on to test it a bit.
Since it became a bit dark by that time, there is only an audio recording of his pop p internet box usage.
