Close on your time 8pm is 8pm

Good evening I'm very upset I was at Ultra Liquors grassy Park today that was at 7.50pm they close at 8pm and the lady with the name of Lucy was so rude I mean what happened to customer service, the guard at the door and the lady named Lucy treated me and 2 elderly gentlemen like dogs chasing us out of the gate they were closing, this issue needs to be seen to I work in retail and this is not how you should treat people especially where it comes to your job, this is unexceptable.
