Free drinks

I mentioned in the beginning of my exchange year that bars offer here beer and sangria for free. These free drinks are mixed with water so it is not very quality stuff. Also some nightclubs have people on the street inviting people to get free shots but also these shots are false. I think it is stupid to offer these free drinks which are false for people. It gives only bad image of the bar when they offer drinks which are not what people are expecting. If they offer something for free they should offer real stuff.
