LOL - Oregonian nannying.

nothing to do with nannying, we just figure if you have to stand in the rain and pump gas you should be getting paid for it. it gives the kids a job so they don't have to steal car stereos. and the oil companys are going to charge as much as they can get away with anyway. we have found that you don't save any money with self-serve, they just use the self-serve option as an excuse to charge extra to have someone pump it.
with no self-serve we have comparable or cheaper prices than all near states (prices are about $.03 cheaper in Vancouver but are at or above oregon prices once you get up into washington. ), and thats their self serve price. you pay another $.30 or more to get it pumped for you in those states.
so we see it like this. if you want the option to pump it yourself you are going to have to pay a little extra for it, and then a lot extra if you want the same level of service you have now.
