Have you met people with Super Attitude?!

yah specially in my work,i'm working in a fastfood chain as a cashier,and i get to meet a lot of different people,and i can say that the only part in my job that is really hard and tiring,is facing rude and annoying customers! like they act so rude as they treat us like their the boss,i know that they're the ones who are paying us,but they should be nice to us so we can give them nice service to,.it's really hard,we can't please everybody.
