Attempted suicide at the laundromat

The show: Medium
The episode: "There Will Be Blood... Type B," aired last Friday on CBS.
What happened: Allison lets Jennifer (Vanessa Marano), a homeless teenager haunted by dreams of a cold-blooded killer, stay in her house, despite objections from her husband and daughters. After a few nights, Jennifer steals money from the house and goes sleep at a laundromat. There, she dreams of the killer calmly killing a cop. She wakes up in such despair from that dream that she tries to drink an entire bottle of Clorox (or some other brand of bleach). Luckily, Allison dreams of Jennifer's suicide attempt and is able to get her to the Hospital in time to save her life.
What has me wondering: Most laundromats I've been to are practically run by Ferengi. Want two drier sheets? Pay a dollar. I seriously doubt that a laundromat owner would leave an entire bottle of Clorox just lying around for anyone to use. However, this doesn't rule out that the bottle of Clorox belonged to another customer. Also, the editing gives the impression that if Allison hadn't dreamt Jennifer chugging the Clorox, Jennifer would have died. Even if we accept there were no customers in the laundromat at the time (one of whom forgot her bottle of Clorox), where was the laundromat employee at?
