oka, it's different here from Japan.....Malaysian style working very very different....I worked in service center before and I can see mostly the technicians work very slow and the what 24 check point...just a gimmick....sometimes work fast does not mean work simply....is work efficiently....
I know there are some service and work that take time but not all...
ya ya...in malaysia windscreen washer topup also wanna charge....be it toyota,proton,mazda (every brand do this)....
even check coolant also wanna charge....
even already using good semi-syn also they insist adding more oil treatment
many B.S thing but only wanna sucks money from owner...
yes i checked this on many girl's car service book...
so back to this protuding screw...u just take picture, mend it with grinder or shorter screw...then logde report at proton care heck..even post to their facebook....so they will know what to improve on next new car....
