Lipstick Answers

In this Horror Novel I’m writing, a 19 year old girl works at a Pub called the Cheshire Cat (Yes it’s legal, if your 19 you can work with Alcohol, you just aren’t allowed to drink it until age 21) anyway, her pervy boss Jerome flirts with her, when she rejects him, he insults her, & makes her lock up at around 10pm as it’s a sunday or something. He leaves her all alone & goes home, as do the last remaining patrons & barstaff, our current main character, Natasha, the barmaid, cleans up a bit, puts stuff away, then goes to the bathroom to freshen up before locking it, (as she’s going to meet an old highschool sweetheart) as she is about to leave, somebody turns the jukebox on, & she is suddenly met with some oldie music. She goes to the jukebox eventually, before seeing in lipstick, it says turn around on the glass, she turns & screams & is attacked by a killer with a hatchet. Long story short, she is chased through pub & jumps through shut window to escape, killed with a hatchet to the back of the head, then the next day, they find she has been partially eaten by guarddogs, let out by the killer afterwards.
Anyway, besides all this: Would a pub have guard dogs to ward off thieves? That & anything unrealistic you see in the description.
