I used to work with an alcoholic, she would make coffee with wine in the mornings, just like a spoon full of instant coffee in a mug of wine. And in the afternoon she would walk around with a fork in her mug like she had a cup of noddles. After she was there for like 2 years my boss asked me if I think she was an alcoholic and I started laughing, he legit had nfi she had been drunk every day for the last 2 years
