(Washington Times) New Jersey investigators accused 29 bars and restaurants of switching out cheap alcohol for the more pricey brands — and, in at least one case, serving rubbing alcohol in place for scotch.

Among the restaurants caught in Operation Swill were 13 TGI Fridays, The Associated Press reported.

Among the establishments’ offenses: Subbing in dirty water for premium-priced liquor. And mixing together rubbing alcohol and caramel coloring and voila — “scotch.”

The investigation spanned a year and included collection of 1,000 bottles of vodka, gin, rum, scotch, whiskey and tequila from the bars, Attorney General Jeffrey Chiesa said in the AP report.
