very much so, i could tell for these reasons.
1: i could smell it on them when they ordered.
2: when they puked before recieving their food, and when i went to go mopp it up after they left, the place smelled like a sick mix of vodka, whiskey, beer, tequilla, and peanuts.... as well as soething else that smelled like decomposing meat.
3: they were stumbling all over and almost hit my car on their way out.
