While prostitution is legal in Nevada, it is illegal in Las Vegas. So, that means that all of the bordellos are outside of the city limits. And, that means that in order to get to them, you have to drive to them and driving of course takes gas.

So, to off set the price of gas, some sporting houses are now offering free gas cards. The idea, I guess, is to encourage visits by covering the price of gas.

Have you ever considered the similarity between having sex and buying gas?
