Had one national call panicked because we got 4” of snow overnight in early November. Said I would do it if they prepaid. They didn’t like it but finally prepaid with credit card for one service. Worked out well for me there. Offered the seasonal contact but I said I needed $1k up front before any work. Again they weren’t happy about it but did change their contract. I still didn’t end up taking the work but goes to prove they can move off their crappy terms.
