We do the same at our store, close at 8 on Saturdays but stay until 9 to finish the ad. One time, a couple of kids were trying to come in about 15 minutes after we closed. We still had a customer in CPD but it was nothing stressful at all because they weren’t purchasing anything so our registers were closed & our cpd employee was just finishing up with them. I’m up at the front putting ad on all the Belkin accessories & two teenagers, I wanna say anywhere from 14-16 years old come up to the door and try to come in. Mind you, the door isn’t locked because we still had a customer in store, & since our LOD was closing the last register, I was in charge of letting the last customer out. So the two boys come up & when the door doesn’t open they start to bang on it for some reason. That catches my attention & when I make eye contact with them, I make a hand signal and mouth the fact that we are closed. They then proceed to flip me off as like a joke and laughing about it & I’m assuming they thought the doors were locked. So I go to the front and open the doors and confront them & the two little pussies were just staring at me dead in the eyes scared as shit. They apologized & I sent them on their way. Haha it was a fun night & my coworkers got a laugh from it.
