What is the main job of the business representative of a pharmaceutical company? Do you want to drink often?

Business representatives mainly deal with some dealers rather than hospitals, and alcohol consumption is still very important. No matter whether you are in the south or the north, there used to be a business executive in our company who threw up and didn't want to drink, but there was still nothing to do. Under normal circumstances, business representatives travel a lot, mainly responsible for payment collection and normal supply.
