Invoice slang: LOF, MPI, R&R, NTF, shop supplies, 'while we're in there.'
Invoice slang
Try cabin-filter, LOF, or flush
service
Lube, oil, and filter. Drain the sump, new filter, refill to the spec on the cap.

LOF is not a 'full service' and not a license to add a flush, an induction, or a cabin filter without a price.
