Treuliodd Ysgrifennydd y Cabinet awr yn gwerthu The Big Issue y tu allan i Costa ar Stryd y Frenhines, tra bu Bethan Jenkins AC, a oedd wedi'i wahodd i gymryd rhan yn yr her, yn gwerthu'r cylchgrawn tu allan i Burger King.
The Cabinet Secretary spent an hour selling The Big Issue outside Costa on Queen Street, while Bethan Jenkins AM, who invited him to take part in a selling challenge, sold the magazine outside Burger King.
