I never could get the hang of bourbon,I prefer scotch or irish whiskey.
as a bartender for 20 years I found that JD usually led to a fist fight or groping,a call to the police anyway.
it was usually over consumed by a young man or men.

we served Makers Mark also and that tended to be consumed by Gentlemen over 30 and at a moderate pace.

if they ordered JD we sent security to stand near the table

if they ordered MM we sent the prettiest waitress over to the table.
