Code does not execute a second " var = getchar(); " if an if is true

Question

Why the code below does not allow me to fill in the 'ext' variable if the established condition has been accepted?

#include <stdio.h>
#include <stdlib.h>
void main(){
    char ext;
    char dif;

    dif = getchar();

    if(dif=='p'||dif=='P'){
        printf("\nVoce digitou %c",dif);
        ext = getchar();
        printf("\nVoce digitou %c",ext);
        printf("\nDONE");
        exit(0);
    }
    else{
        printf("\nShame on you buddy");
        exit(0);
    }
}

output :

P

Voce digitou P
Voce digitou

DONE
