Happy Birthday Grandma

Friday, April 8th 2011 Today is my late grandmother's birthday. I am thinking about her a lot today... I stopped by a different gas station today since the usual one was packed with cars. We're heading out of town early tomorrow morning, so I want the tank to be full before we get on the road. The guy who filled it up was nice and I gave him $1. Gas prices are so high that $1 seems minimal compared to the total bill, but it is also because the prices are so high that every extra dollar counts. Does everyone else tip the gas station attendants? How much is the average amount? Perhaps I need to step it up. Peace :)
