A couple of weeks ago a landscaper drove his Bobcat through the electrical and water lines from the house to a detached wellhouse. It turned out the electrical conduit terminated at the bottom of the meter box -- the installer had used the service entrance conduit as a convenient path to the main panel. So, to replace the subfeed, I had to unseal and open the meter box to get the old wire out. (I took the opportunity to penetrate the wall in a separate place for the wellhouse circuit, leaving the meter box "clean".) I called the POCO the next day to advise them I had broken the seal. They said no big deal, they'd replace it when the meter was read (the 25th or so).
Around here, we would never use loppers to cut a service drop. We carry rifles in our pickups for that .
