They add mercaptan which is like 1000x the rotten egg smell of H2S.
Mercaptan is a group of compounds, more than one of which are used as gas odorants, so in some places, gas smells of rotten eggs, similar to H2S, while in others gas doesn't smell like that at all, but a quite distinct smell that's reminiscent garlic and durian.

you are lucky to not have smelled metacarpan (which is what is actually put in). Much much worse than H2S

I have. It's worse no doubt. But it's not the smell of rotten eggs. My comment was meant to be tongue-in-cheek to correct the mistake of saying "H2S" in the GP comment.

If that is the case (and I have no reason to believe otherwise), I apologise. Should work on detecting tone better.
I am 100% sure that the smell they add to natural gas does not smell like rotten eggs.
