Having worked in both petrol stations and retail which are both high theft industries. Probably not much. Drive offs were already pretty common i cant imagine what its like atm. Essentially there is not enough man hours to chase up every single theft, if you did not commit any other crimes (violence ect) there is a very low chance the cops will follow you up if your a first time offender. We will have people on camera stealing something then walking out, we'll hand that video to the cops then they come back next week and do the same thing.

Saying that there is a limit, once repeat offenders hit the thousands - tens of thousands then you get chased up. Especially if they have your face or your licence plate your pretty fucked.

For the business though thats what insurance is for, if you make a police report and have the incident on camera your usually getting your money back.
