Sheetz review: Security

I went into into sheets today around 4 o'clock after my shift as a nurse in my scrubs. I opened up one of the refrigerator doors as a security person behind me yelled across the store DONT DO THAT! In a mean tone. The door had a small dont open sticker on it I failed to see as I didn't have my glasses. It was a young white male early 20s. I wouldn't have said anything but I had entered the store earlier that day and he literally spent his entire shift in the corner watching YouTube on his phone at full volume.
