I have rage quit two jobs.
A long time ago I worked in a supermarket as a personal shopper. It was a pretty decent job, early start (4am) but an early finish, so it felt that I had the whole day to do whatever I wanted, though I was tired.
Skip ahead to Christmas eve, where everybody apparently has left their huge shops until the very last minute. Not only through our online service, but also in person.
Imagine this: You are being pushed to complete orders as quickly as possible and being called out for being slow, not only that, but every aisle is so full of people that you literally cannot push your trolley through them. I literally couldn't move or do my job. I'm fairly embarrassed to say that I walked out, didn't even tell anybody, and to my surprise I never got called out for it (I think it was too busy to notice) and the way the system worked, one of my colleagues would have just got the order and completed it without me.
The first job I ever quit, I must have been 16 years old. I was working as a promoter for a bar in a small town, essentially walking around with a sign, hanging out flyers, etc. ironic that a 16 year old is advertising a place they wouldn't otherwise be allowed into, but it was cash in hand and pretty dodgy.
On my first night I was promised $50 for my work, but ended up being given $25 because they said it was a trial night. Suddenly my nightly salary is $25 and as a 16 year old, I'm a bit too scared of this dodgy guy in his car that was paying me to ask for the full amount.
Skip ahead a couple of weeks (I work maybe 3-4 nights a week, hours are like 10pm-5am) and tonight, it is pouring down with rain, I'm freezing cold, my uniform involves a t-shirt, and it is genuinely just a horrible experience.
I go to my boss, and tell him that I'm gonna go put my coat on and he says that's not part of my uniform. I get a bit ballsy and tell him I want the extra $25 for the night before, and he said he never promised me anymore money than $25. So I walk home, in the rain, feeling hard done by but also like I learnt a valuable lesson. I never worked for less than I was worth after that.
