i need advice and i can't find it anywhere else on the internet our computer support guy is plump and very long waisted and when he crawls under the desk to unplug things his shirttail pulls out of his pants and his waistline descends exposing the crack between the worlds i really really do not want him to have his pants slip off while i am in the area i feel it could damage our professional relationship but last time it came awful close what advice can i give him that would prevent this
