What do you mean, you don't want to sit under the fan?

I had another amusing dream last night, this time a classic waitress stress dream.  So you know I work a night or two per week at a local pub for cash and socialization, yes?  Well, this dream outlined pretty much everything that could go wrong.

It was a slow night, with no customers, I was literally playing hangman with the bartender to pass the time.  Then a table of four came in (hurrah, something to do!), and I seated them and quickly realized that there were extra bits of paper to hand out with the menus which took an extra confusing few minutes.  When I finished that, I realized that several other tables had filled up with customers seating themselves and then looking extremely impatient when no one had brought them their menus.  The other server was all like "you're in charge of seating everyone, you figure it out, which tables are mine?"  Then we realized that there were no more menus.  Sooooo may as well bring them water while the menu issue is being sorted out, right?  Turns out that the faucet and ice machine were waaaaaay back in the suddenly labyrinthine kitchen, and one can only bring one pitcher out at a time and its going to take for-ev-er.  But in the kitchen there was someone laying on the table with a massive gross head injury being attended to by all the kitchen staff.  Avoid that, realize no food is going to be coming out any time soon.  Heading back into the restaurant, I saw that the table of ten with the reservation had arrived and were seated, and the rest of the tables were also full with increasingly-impatient customers.  No way I can get to everyone since they all arrived at once.  Then the table of ten starts complaining that they want a different table because they don't want to sit under the fan.  There are no more tables to move them too because all the other tables are full of people waiting to be served.  The manager gives me the stink eye when I say I need some help.  THEN....I realize this is a dream and I can wake up and actually not have to deal with any of it...

Things to think about:
1) Remember, tip your servers well, because if nothing else they are getting paid $5 per hour to have dreams like this.
2) How long will I last at this job if this is the kind of dreams it gives me?
3) I wonder if the fumes from priming the bathroom prior to repainting had anything to do with my dreams?
4) I recently listened to a fascinating Radio Lab podcast about lucid dreaming.  I'd like to know more about that, since I sometimes have dreams where I can realize I'm dreaming and change them or make them stop.
