You're doing what you think is the safest thing for your child. Others may think differently and that's ok too.

I usually try to get DH to fill my car up on the weekends when it's the family car and we are together, but if that's not possible, I lock the car with Sam inside while I go in to pay. I try to use a quieter servo so that I'm in for as little time as possible even if that means paying a little more for my fuel. If it's a really hot day or Sam's upset, I carry him in with me, but I find it makes the process of paying much more difficult when you're juggling a baby in one hand and your cards/pen in the other.

I've had others at mothers group with more children and older children than me say that they think it's safer to leave the children in the car when paying for fuel. Can you imagine taking a couple of kids who walk safely through a service station? I certainly can't!
