My thought has always been that if they're not giving me the option then I'm not going to tip.

that's kind of the way i've felt about it too. tipping is generally something you give for someone performing sort of a luxury service for you that you could've done for yourself otherwise, but in nj you can't pump your own gas.

however, when it's the middle of the winter and it's 10 degrees out and those guys are standing out there pumping gas, i feel like a schmuck if i don't give 'em a buck or two.
