Most HAL customer service staff are behind the scenes (although trolley operatives are visible, for example), as are engineering (who maintain the infrastructure) and other operations staff (responsible for airfield safety, non-T5 stand allocation etc.).

Sales staff in shops are employed by the retailers, not HAL. Ground staff are employed by ground handlers or airlines, not HAL.
