Ha, something similar happened to my grandmother, though they claimed to need to read her meters. My grandmother is in her 90s and has a lead a hard as fuck life, she takes zero shit. So she immediately thought it was odd that they didn’t say which utility meter they needed to look at, nor did their uniforms have anything more than vague identifiers on it. So she said oh? which meter? What utility? She said they stammered a bit but said water, and she said, ok, the water meter is right there, pointing to the meter in the back of her car-port. Then they tried to come up with some BS about how they need to get the “other” meter readings at her water-heater. She knows that isn’t a thing. So she said there isn’t such a thing, you need to leave. They immediately started to argue and she said “I have no qualms shooting two men trying to rob me”. They left, they were yelling they would tell the police, their utilities company, the department of public works, etc. She said she needed to take her heart medication right afterword, but was otherwise fine. Well guess what? Nothing came of it. Thing is, she keeps a small gauge shot-gun next to the door and would have, indeed, shot them if they tried to get inside.
