When you enter the world you want to go around the back. Through the left alley to the back of the building Put your mask on. In the back there will be guards, two at most. Kill them or use your domination skill. Make your way through the window and put whoever inside on the floor.
Now you can steal everything in the room without anyone noticing you (except if someone walks in to the room which happens occasionally) now make your way over to the room adjacent to the one you are in and start stealing the stuff in there. If there are any witnesses in that room cable tie them as well. There should be a safe in one of the rooms. You can start drilling that without anyone noticing you.

It is now time to go into the main store. Take out your silenced gun and shoot some rounds into the ceiling, take down the guard by killing him or using your domination skill. Make sure you Answer his pager.
Now it is time to attend to the hostages, cable tie the ones that are in the front of the store first and then move them into the back of the store so that no pedestrians can see that there is a robbery going on and.

Congrats! The hardest part is over. Now it's time for the easy part, smash it all! and take everything, always keep an eye on the hostages who are not cable tied so that they can't call the police.

Put the bags in a neat pile on the floor and fix the drill when it needs fixing. When you have all the bags possible in a pile. Start running to the van and throw the bags at it. If you are afraid that the un-tied hostages will call the police when you are away, just plonk down an ECM jammer in the store and they won't be able to make phone calls. Take your last bag and go over to the van and throw them all in.
That is it. Simple and Fast. If you collect all the bags, take all the loose items as well as have the Dead Presidents perk for more value you should get up to $250 000 and 53 900Xp.
Note that this is easier the more people you are. More people equals more cable ties and bag carriers.

Good luck.
