Water found! Have the offerings to Thai spirits helped?

When our first attempt to drill a new well failed, I was blamed, since the ignorant Farang had not adhered to the local Thai customs. We had not performed the animist rituals of offering goodies to the local spirits. This time around we offered boiled pig heads, rice liquor and other delicacies to the invisible powers inhabiting our land and this second drilling not only went smooth, it was a huge success. What does this tell the non-believer?
