need to rant

So, I got an application from a gas station the other day.. And he told me i just needed to be "20 And a day" and to come back to talk to the manager which, I turned 20 in February.. fast forward.. I go this morning to turn it in, and I went to hand it to the guy employee, the girl manager looked at me and said "no. shes not old enough." while like shoo'ing me away and shaking her head no, for him to not take the paper from me. I said UMM I'm 20 years old and she said "maybe she is old enough" then proceeds to tell me she's not gonna hire me. People are so fucking rude. 😠😠😠😠🙄 rant over. feeling very irritated. I shouldve went off on her.
