Sharp drop in laundry usage

[Sam R.]

Where can I find laundry room usage data and statistics. I have some buildings in 2 separate towns with each having a pay laundry room. For months since I started tracking, there was typically a load a day on average. Suddenly it all stopped and there hasn't been any laundry for 3 weeks. I have double checked that everything is work and no tenants have complained. I would suspect tenants are up to something, but it has happened in both towns. So maybe it is just a seasonal thing?
