Assuming everybody does what they are doing now, the situation will remain the same as it is now. In other words, people will still go to their jobs and do their work, the stores will give them stuff, and so on.

In practice everything would collapse, for the reasons implied by gjm in his comments. Namely, since the people in the store don't ask me if I have been going to my job, just as they don't do that now, that means I can get away with going to the store and getting stuff, but not going to my job. Or, even if I do go to my job, I can take a lot more stuff from the stores than I'm actually contributing by my work.
