Usually pag nagpapagas ako, i tell the guy the amount and type of fuel to fill(XCS, unleaded, etc.) Di ba naisabi ng friend mo dun sa magaling na gas boy?
Maaaring me kasalanan din ung friend mo for not being alert enough to check what fuel was being loaded...but the fact is that you brought this up with the gas boy, who fed you wrong information, thus making a bad situation even worse.
ireport nyo yan sa owner ng gas station, or the franchiser...supervisor pala siya e wala naman palang alam, nagmamarunong pa. Di pala maganda training nila sa tauhan.
At the very least they should drain your tank and load the correct fuel.
