I work for 4 moths now at a big supermarket in Belgium as a technician fixing stuff in the supermarket, there was one of the fridges that was completely frozen and i had to unfreeze it and while removing the blocks of ice there was one of those that i tought that it could could be removed easily with my trusty screwdriver.
I pushed and i made a hole in the tube where the frozing gas circulates and it became a mess.
The right hand of the director came later to me when i was with the specialist reparator of fridges (don't know the name in english sorry) and told that there won't be a next time. I'm a bit confused and i fear that i will lose a job that i like doing, but the upper ups are a bunch of assholes.
