Karaoke and Bartending

So my dream last night started with me showing up late for work. I worked at a Karaoke bar as a bartender. When i got there, there were two half made drinks sitting on the counter and two people waiting for them. I sprayed some whip cream in them, but the whip cream was almost gone so it just went everywhere. I heard two boys complaining about the bartender (me) not being there on time and talking about just making their own drinks, so I followed them behind the counter and told them i was the bartender, but that they could stay and make their own drinks because I really actually had no idea how to make drinks.

So they whipped out a textbook looking recipe book and started flipping through the pages when another guy showed up at the counter and told me he was a professional bar tender and that he would help me. then he said "first of all you cannot be looking at these sort of things" and he slammed shut the textbook the other boys were looking at. "or these things" he whipped out a grocery store news paper ad-thingy and started scribbling out any sort of liquid while mumbling under his breath "you cant look at milk, you cant look at orange juice, you cant look at soda pop, you cant look at water" and then he said "you just sort of, go for it. Look at all the possible combinations you have" as he pointed at a wall stocked with different flavorings "just mix them together and some of your creations will be terrible, and others will be great" and then he ordered some drink, which i had no idea what it was.... then up walked my friends Joe and Marinda. They ordered a couple virgin drinks (of course) and then Joe told me that Jer was there and that he would be singing next. So Jer got up to sing, and that is when i woke up.
