A man is warning drivers to pay closer attention at the gas station after spotting something unusual at an H-E-B pump.

Marvis (@marvisdss9h) shared the discovery in a recent TikTok video while standing at the gas station.

“Shoutout to the person who’s putting these videos out,” he says at the start of the clip.

Marvis then zooms in on a screw attached to the gas pump and explains why he believes it is there.

According to Marvis, when someone inserts a screw into a specific spot on the pump, it can allegedly prevent the machine from properly resetting after a customer finishes paying for gas with a card.
