Services Fault

avatar male m

Seeing Denmark Open yesterday & saw some crazy fault happen like on Ahsan/Hendra & Zeng/Huang.

On pro lv, is it possible for god like human to had fault on their serve. Yes they are human & human makes mistake but having fault again & again, it just ….

But regardless what it is, im just curious myself. Is it the services judge that are being to strict, or the other judge are to lazy & didnt did their job letting all fault happen so all player think their serve are fine.
