Glad nothing happened to you. There's all kinds of people in the casino trying to make a quick buck by taking advantage of other people. I agree with your observations, but also, Caesars LV is like 10x bigger than Caesars AC. So it's relative that you may not see security as often.
At the end of the day, they don't care if other people are trying to steal your money. Only if they are trying to steal the casinos' money. If you started winning some money on the slot machines, security would be there in a heartbeat.
