I'm Guessing It's the Latter

It's always something with customers. First we have people fumbling with pennies and now we have people buying a set of double A batteries with a $100 bill. Seriously, people? I don't have that much cash in the register. I just called for a refill on bills two minutes ago and now I need to call again. Derp-mart would accuse me of stealing in a nanosecond if they weren't constantly watching me on surveillance  I'm not sure if they're always watching or if it's cause I'm Black.
