Ah it's all there.
I remember my time as a Bottle Shop Attendant, and it was strikingly similar to this, especially the wrinkled clothes, vacant stare and shoes. However I never had a scanner or a customer assault me (I do know of a person that did get hit a couple times though). All in all, a great image, and the only thing I'd recommend if you would further develop this is to add the store background, all dimly lit and such.
