Not booze but i received a similar lesson a year or two ago next to the Vatican. My girlfriend and i walked into a nearby sandwich shop at lunchtime. We were rushed to our table by a member of staff. 2 rolls and 2 cokes. 40 euros later...
We live and learn.

A pint in Paris is usually a pricey affair. People take advantage of happy hours when/where possible. A pint can range from 6 to 12 euros as far as i'm aware. Pitchers appear popular as well.
