Tavernaphobia

Tavernaphobia (from tavern), also known as coponaphobia (from Latin copona, "tavern"), is the fear of going to a bar or tavern. It is commonly suffered by people who suffer from methyphobia (fear of alcohol) and zephophobia (fear of beer), since bars and taverns are where people commonly drink beers. Another reason for the fear is that bars are commonly crowded or the way people act there. More far-fetched reason is that people may fear having a good time.
