Pumping Gas Question?

   I hate to pump gas.  However, I do like to drive my car.  So every week or so I find myself at the gas pumps.  It makes me very happy when I can time the chore of pumping gas when my husband is driving my car so he can do this for me.  I know that if I monitored the gas gauge a little closer and then asked my husband to do this for me he would.  But for me, I am usually in a hurry to get to work.  I  look down at the gauge and then I wonder if I am going to make it to work.  Long story short,  I have recently discovered that there is a rumor that some states like Oregon and New Jersey do not have self-service gas stations.  That it is against the law to pump your own gas.  So I began to wonder how many states have laws such as this?  Does it affect the price of gas?  As a kid growing up, I can remember having gas stations with attendants.  My grandfather was an owner of an Exxon gas station (at the time I think the name was Enco or something like that ) and he would pump gas for the customers.  That was a long, long time ago.  Now I do not think there are gas stations here in Texas where someone comes out to pump your gas     So I thought I would throw out this question – Do you live in a state that it is against the law to pump your own gas?  Or is this just an evil rumor?  How much do you pay for gas at a self-service station vs. a full service station?
