I've held several jobs in my relatively uneventful existence. Office lackey (which is actually a very decent job for a 16-year-old), cash register monkey (which, I guarantee you, sucks big time), dining hall monkey, child wrangler, and most recently, recycle-bin emptier. Now, back to dining hall monkey. I was employed in the position of student employee in my college's main eatery last year. My duties were to stock and serve food, maintain the drinks station, occasionally prepare food (but very occasionally), clean up the stations afterwards, and stock silverware. Never all at the same time, mind you. Now, in my second semester last year, I did a great deal of stocking silverware, which includes not only forks, knives and spoons but also napkins and trays. In my tenure as Main Student Silverware Person, I learned much about myself, primarily in the field of Things That Irritate the Monster. Repetition of said acts lead to Pissing the Monster Off. So, without further useless ado, I warn you not to do the following, lest you incur the wrath of the little redheaded X-Force fan: 

Drop your silverware on the floor. 

Leave it there. 

Drop your napkins on the floor. 

Leave them there. 

Stick your hand on the stack of trays that the Silverware Girl would like to refill, and leave it there for more than 1.5 seconds. 

Take napkins off the stack that the Silverware Girl is just loading into the dispenser. 

Then, drop them on the floor and leave them there. 

Blindly pick out a fork and then, upon realizing it is a fork and not another type of utensil, stick it back in with the spoons. 

Choose the area around the main silverware station as your gossip spot when the Silverware Girl is trying to refill the trays. 

Crowd around her while she is refilling one of the (six) napkin dispensers, while failing to notice the other five that don't have a dining hall employee standing in front of them and who will need to escape to do the rest of her job momentarily. 

Leave the top tray on a very high stack because said top tray has a fruit sticker stuck to the back of it.
