Dollar General review: closing the store 15 mins early

on saturday july 20th, 2029, at 8: 45 i arrived at the store. i was stopped at the entrence by a employee . she stated that they were closed. i asked the employee what time do they close.she said 9.i told her its 8:45 i still have plenty of time. she told me the register shut off automatically . thats a new one on me! i told her i just need 30 seconds .then she stated its already a line and i wont be out in time..i call bull crap on that.. i just want the company to know how their customers are being treated..thank you in advance for addressing this issue .
