Translation: her apartment in San Diego doesn't have washer/dryer hookups.
The last time I did laundry in a laundromat, it was three dollars a load, plus the time I spent hauling my crap up and down to it, and the time wasted waiting around said laundromat. There's no net benefit to using an outside laundromat at all.
In order to find out what is leaking electricity you do not know is used, call the electric company. They will come in and do a search of your home or apartment to find out every darn thing that in the place that even when you think is off is still causing a leak.
Neighbor of mine was upset at the electric bills, seems the landlord when installing washer/dryers and the Electricians "Accidentally tapped in to their line".
Every time others used the washers/dryers the electricity to run them was sent to their line.
Got to be interesting on who was responsible, the land lord or the subcontractors that did the wiring.
Heard about a family whose neighbors had a family living in a very large travel trailer in their back yard.
They vacationed away from home 6 months of the year. They kept utilization's on to prevent frozen pipes and keep the the security active. They came home when when they were billed for $200 bucks for one month. they came home home to find a PCV pipe had been run into their property up to their out side electric outlet..
Call the experts in your company when things go about odd, same goes for Cable company, why pay for some others usages on your dime.
