Input: Text: i was having a shit day at work and things weren't going my way. i started 2 weeks ago and was  trying to impress my boss. so i thought i would be helpful and collect all the glasses from the top of the bin (the place i work is a giant shared restaurant space and the cleaners just put the empties on top of the bins)

so i grab a tray and fill it with glasses. a lot of glasses. all stacked. i used to be a waiter so i was confident i could carry it.

i was wrong.

i walked across the front of the bar in front of my boss.

the glasses were wobbling. 

my boss tells me to be careful.

the glasses were now swaying.

i stop to try and balance them which only sends all the glasses flying and shattering on the floor. there must have been about 5 seconds worth of smashes.

here's where things go really downhill. the smashes were so sudden and loud that a kid sitting on a table near me absolutely shat himself and threw his orange juice in the air, which of course landed on his new iphone 6.

there was silence.

the kid just stared while his dad violently shook the phone trying to get the juice off, yelling at him for ruining it after two days of use. i felt so bad! his mum gave me a deathly stare and they got up moved their food to another table.

to top it off i couldn't have looked like more of a twat in front of my new boss.

pat on the back for me!
