Many employers do not want employees who make bad decisions.

Ah, the old "You're not perfect. You're fired"!?!?

Probably more along the lines of: you may have attracted negative attention towards us, which is not good for business, so you're fired.

All it takes is one complaint from a good-sized customer.

This is not an economy in which firms can afford to lose business due to easily-avoided mistakes.
