ok - so speaking from experience, our boss dulu2 also have driver -

Driver #1 - was office dispatch, some time office not much work for him - boss will ask him drive around - he can borak2 with bos and the passengers la, fren and family, so some time gossip2 he can spill some kacang he was single, and willing work till late - but after kahwen, he really struggle to juggle - in the end he left to his own transport/logistic thing, iinm lalamove but long time already.

Driver #2 - this one was 100% professional, purely to drive the boss only - even came with his own uniform, and GLOVES - yes, like you watch those Jason Statham transporter movie, very professional, no simply chit chat borak in car one - while it give the orang kaya vibe, not very flexible - 9am to 6pm means, just that, no OT or etc unless paying way higher rates for the extra hours. This one never step into opis other than the 1 time he came in for interview. He just spend whole time standby around the car - what boss like is he really jaga the car la, smoke also is outside, no smoke/makan/minum in the car - if boss not go anywhere, he will prompt to send for wash polish.

very different 'level' of service but same driver job scope but yea, like evrythg else - if you using a 3rd party - there will be risk la - is how you assess the individual during interview, and dont skimp on running any necessary background checks IF you feel the need to
