Why is that relevant for work? Are you looking for labor, or for a date/drinking buddy?
Social and communication skills are important but I can be professionally communicative for work ralted topics, and still not want to have a beer with you after work, because it's my free time and I have other interests than you and other things to do.
Unless the company choses to have the beers/drinks during working time in which case by all means, if you pay me to drink on the clock I won't say NO.
