Is it normal that i have duo personality during my work ( shop keeper)

I've been working as a shop keeper for about 6 years, and believe me I am a easygoing person, but during work , sometimes I am very nice and easygoing, but othertimes, I show myself as a cranky , mean, person.
I am not 100% sure why is that. maybe I see too many different people, and people sometimes can be very stupid, rude, ignorance and even very mean to me unintentionally. or , maybe sometimes I have to do multitasking, which is the last thing I want to do in the shop ( example , stock shelf while take care of the till. ), people may think Multitasking is not hard , but in reality, it's extraodinary annoying ( especially for male ) , then, these two elements are making me in downward spiral , life makes me become a mean , cranky person.
Is this normal, I don't think anyone who is not working in service industry would understand what I am saying here, just to be sure, for whom is working like me, is this normal ?
