You COULD start by showing up ontime! ;-) No, really, as a "mixologist", I'd reccomend a different type of wine than normal, (IF the group you are with like wine, otherwise, match the liquor to the taste), OR if you really like to spruce things up, try making your ownwine/ beer and surprise everyone! Yes, it may take some time, but if you are always late, than maybe it's worth it!
Try to only bring enough so people can try a taste of it, and "tickle their tastebuds" with it, that way, if they don't like it, nothing lost, if they do, you'll be the talk of the hour!
