New Jersey state officials found a bar serving rubbing alcohol mixed with caramel coloring, and served as scotch. As part of a yearlong investigation called "Operation Swill," state officials have been raiding a number of bars in New Jersey investigating whether bars are switching out cheap liquor for top shelf, and overcharging customers.

So far, they've raided 29 bars, including 13 TGI Fridays, that are being accused of substituting cheap liquor for more expensive brands. So far they've collected 1,000 open bottles from the wells of bars — the findings are very surprising. Not only did they find rubbing alcohol but they also found a number of bottles filled with dirty water, according to the Washington Post.

"This alleged scheme is a dishonest ruse to increase profits and is a slap in the face of the consumer," state Attorney General Jeffrey Chiesa told the Washington Post.

The establishments in question are required to turn over their records to state authorities within the next seven days in order to determine how many patrons were overcharged and by how much. They must also inform the state which employees were working on the days the samples were taken.

The authorities conducted the raids on 63 establishments by ordering drinks neat — without ice or mixers — and then covertly taking the drinks as samples. They found that 30 of the 150 samples were not the brand that they were being sold as. The establishments in question face suspensions of their liquor licenses and possible revocations.

Rubbing alcohol is also known as Isopropanol, and is poisonous to the human body. It's normally found on alcohol swabs, cleaning supplies, paint thinners, and in perfumes. If you ingest it, it's important to contact a poison control center immediately since it can cause coma, low body temperature, low blood pressure, low blood sugar, rapid heart rate, unconsciousness, and vomiting, according to the National Institutes of Health.
