Do I have anything to worry about if I took cash then put it right back?

I was in an office doing some work and they were dragging their feet on getting money for supplies to complete the job. I saw petty cash sitting on the desk, so I took it and went to talk to the office manager, she couldn't find the keys that were needed to complete the job so I put the money back. I probably should have just told them that I saw the money and to stop dragging their feet. Every dollar was returned right away. However, my paranoia drove me to write this question, I didn't intend on keeping the money for myself, I only wanted to do the job. There hasn't been any word on it at all, but I haven't received a call back from them (which may be more foot dragging). I'm just paranoid they may make up some story. No one saw me take it or put it back (I didn't see cameras, but these days they are tiny, I'm telling the truth in that I put it back and never took it with the intention of keeping it, do I have anything to worry about? I know it wasn't the right way to handle the situation, I would appreciate your help in this matter.
