I know in So Cal Edison land, nothing happens in a timely manner. I've called for a meter guy to come out and all but maybe 2 times, they've tried to "schedule an appointment (usually in 3-5 business days)" while someone is left without power.
I have no problem snipping seals if there's a reason for it, and occasionaly I'd grind a lockring off and replace it with a regular meter ring. (Never heard any complaints...)In San Diego Gas & Electric land I had a lineman give me a whole box of seals, and told me if I needed to break a seal, just put a new one on when I was done
Some of those San Diego seals ended up used in other places, surely to baffle some attentive meter readers in LADWP areas and elsewhere
