For some reason, Mary Kate Olsen looks REAL shocked when she discovers someone is watching her pick out bottle after bottle of champagne at the local liquor store. Whatcha' hidin', Mary? Apparently, Mary and friend in black are buying a LOT of alcohol, as her friend can only withdraw $200 from the in-store ATM, and she must also take out money to foot the bill.

Another portly gentleman (a big guy with goatee and earing) emerges from the back office -- manager? employee? -- and attempts to shush some photogs away who are standing outside on public sidewalk, and actually threatens grievous bodily harm. (Can you make that threat again, this time a little louder, and towards the camera, sir?)

Finally, when Mary Kate and pal emerge from the store, they care little for traffic laws and almost cause an accident by jaywalking across Doheny. Way to go Mary Kate! After all, you're a celebrity! Why should you have to follow traffic laws like the rest of us peons?

Happy boozing!
