What's the closest you've been to quit / what made you quit?

For me (Still at THD) it was when they gave these to me (19 yo new hire with no reach truck license) to put overhead with 90 minutes left in my shift. I was told "deal with this" because none of my co workers were "able" to do it.

I ended up trying my best but had to stop after like 30 mins of going up and down the ladder. (Bad knees)
