Oh yeah, in my construction days in small towns, I often went for bar lunches, as they were cheaper and at times delicious.

A little guy would timidly come in and ask for a beer. After the beer a double and after that another double and so on.
What a transformation, as then he suddenly transforms into a very loud lion.

The bartender would phone his house and his missus would arrive indignantly to slap him around and then to take him home :)

Only one of many that I have watched my friend!
