Guy paid me $60 to fix a PC that just had his monitor plugged into the motherboard
He'd been running on integrated graphics for 8 months and thought his $400 card died, so I moved one cable and he almost hugged me. What's the easiest money you've ever made on a house call?
Moving one cable for 60 bucks is a steal for him honestly. People panic and assume the worst when it's usually just one dumb thing unplugged. That's basically free money for you.
Would you believe people still pay that just for someone to push a power strip button? @chen.adam is right, it's basically free cash for the "tech guy" who shows up and plugs the router back in. Easiest 60 bucks anyone ever made.
