Your shitty makeup is gonna get me fired

If you work as a cashier in a store that sells age restricted items such as alcohol you may get underage girls coming into the store with tonnes of makeup on to make themselves look older. This can result in you not asking them for ID because you think they look old enough to not need it but you end up getting fired anyway because they are actually underage.

For the guys, it is "your shitty beard is gonna get me fired."

Underage girl: *Places bottle of wine on counter*
Cashier: ID please
Underage girl: But I'm 30!
Cashier: Nope, your shitty makeup is gonna get me fired!
