I find myself explaining why I'm not drinking all the time, when just a no should be enough. And I don't like it.

I've worked as a server before and I was personally never told to push people to order alcohol,but I know that happens in some places, because like you said the mark up.

I would be very uncomfortable with a server, especially a male one pushing alcohol on me like that. And I can't believe a waiter went as to bring you booze when you said no, I wouldn't be okay with that.
