That's my 'Cashier Face.' If any of you have been a cashier, you probably know what I mean. It's just a universal face that I give to all of the creepy, smelly, mean, rude, old people that come in droves during your shift.
I promise I have a normal face for the rare, elusive, 'nice' people.. but it's a harder face to capture than the above.
Hey. You deal with people getting pissed at you over the price of spaghettios and butter, and try to be nice to them.
