Many people go out for a drink after work in order to relax. They want to drink a cocktail or two and then drive home. Others may want to go out for a drink when they meet a new person and they want to get to know them. There are times when people should stay away from cocktails. This is when a person is an alcoholic and they over drink many days of the week. They should not drink a cocktail.
Another type of person who should not order a cocktail would be the beer drinkers of the world. Those who prefer beer to cocktails should probably order beer or they probably would not like the cocktail. I would drink a cocktail a few times a week. I don’t think that would hurt anyone.
