hmm, you seem to be ill equiped for a robbery right now, but no matter
a) dive tackle the nearest gaurd, take their wepon, proceed with robbing
b) just roll with it, use intimadation, be a bad ass, they wont dare mess with you
c) theyre pretty distracted by the grue corpse, be sneaky, sneak into the vault, you gotta be sneaky, sneaky
d) "hey everyone i'm a bank person, ok, ima go in here and take some money, need it for bank stuff, kay, ima bank person!"
something somthing, i dont know, whatever
