Smell Gas?

I've reported four (suspected) gas leaks in the road/pavement recently.  

It's quite easy to report them (after you have plucked up the courage to ring the "Gas Emergency Services" on a number ending in 999). What if they weren't really gas leaks...I hope there's no such charge as "wasting gasboard's time".

Outside, gas disperses so easily that the smell is quite faint. I wasn't sure if the smell was gas, or just a pretty flower or exhaust fumes.

I saw that they did dig up the road in at least one of the places I reported it, but that's the only feedback I got. It would be nice if they would give me a ring or write to just say "you were right, they were really gas leaks, oh and thanks". The lack of response makes me wonder if my nose is imagining things.

All four leaks were in busy streets and must have been passed by thousands of people. I've been noticing a faint smell of gas for months myself before reporting it.

If the gas companies really do care about gas leaks, there are two simple things they could do:

1. In their marketing for the gas "emergency" number, make it clear that you can call this number to report a leak, even if you don't think it's a life threatening emergency. 
2. Tell the people that report the leaks whether or not the leak was confirmed. Just tell me whether the smell was real or my imagination!

This is of course in contrast to Yorkshire water who did phone me up after reporting a water leak to confirm that it was a leak and thank me for reporting it.
