You should be concerned about being fired, for two reasons. One, if you're fired for theft (which is the cause they would give), you're going to have a hard time collecting unemployment.
Two, if you're fired for theft, there's a good chance they'll drop your name into a shoplifters database - as happened to one of our other posters hereabouts - making it extremely difficult for you to find other employment in the retail sector.
It's not a criminal record, but if that happens, it might as well be one, as it will cause you difficulties in similar ways.
